    What would YOU do for an engine build in my situation?

    Yeah, it's definitely not cheap. The build is still on but going slow. I did finally get my crank specific oil pump for the MMR 4.75 crank though. So now I can actually send the block off for sleeves and assembly. That'll be a while though, unfortunately. Over Christmas I did do some work to...

    What are you asking for the heads?

    What would YOU do for an engine build in my situation?

    Also, for anyone following the build, I'm now planning a 6r80 swap. There's plenty of guys going FAST with them and I'm wanting this car to be daily drivable. My 08 v6 is auto and I'm loving it compared to the tr3650 lol. From doing limited research on the swap, all I need is a 2013 f150 6r80...

    What would YOU do for an engine build in my situation?

    For the heads, I'm still unsure. I'll definitely be sending them for some work, but gotta decide on what I want. Some say the upgraded valves being bigger cause shrouding issues, so I need to learn more about that. I also need to find out what springs are best for what I want. I've read about...

    What would YOU do for an engine build in my situation?

    So, about the crank setup being a stroker, it is more stroke than stock but not huge. It's literally a Forged Steel Coyote 8 Bolt Crank from a Boss 302. It has 3.650 stroke vs 3.543 stock and 3.750 in the Eagle 5.0 stroker kits. It was the obvious choice for me because I wanted more rpm. I've...

    What would YOU do for an engine build in my situation?

    I'm still SLOWLY acquiring parts needed. MMR said my crank will be in within the next 2 to 3 weeks, so pretty pumped on that. I ordered my 3.7 bore pistons last week, MMR quoted 10 to 12 week lead time on those aswell, unfortunately . But, now all I lack is a proper rod. Once I decide on a rod...

    Comp 127650

    Who here runs or has run the 127650s? I keep reading about broken rockers, springs, and chewed up lobes. I want a super aggressive chop at idle and these are supposedly the top dog, just wondering why people have so much trouble with them. If you've used these cams with success, what's the...

    Anyone here ever installed a 4.75 crank?

    Just ordered the MMR 4.75 Crank and after doing some reading, I've seen posts about a few issues people seem to be having with it. I was wondering if anyone here has installed the crank themselves or rebuilt an MMR assembled block and could give me some pointers. I've specifically read about...

    What would YOU do for an engine build in my situation?

    Luckily, the new crank comes with Clevite bearings. I'd only bought the King XPs because a No Prep guy said they were pretty good. Said he drove a few miles home after an issue with no oil at all and they didn't fully fail. So I figured they be good insurance if I did ever window or crack the...

    What would YOU do for an engine build in my situation?

    Well, I want to be able to daily it during the summer and be able to put the slicks on and run a decent time at the track every so often. I live a couple miles from a nice Quarter Mile dragstrip, so that's definitely gonna be something I want to do. As for budget, I have a few grand a month I...

    What would YOU do for an engine build in my situation?

    Well yeah, even a mild cam requires phasers to be locked or limited at a minimum. Anything with a bigger lift has to be fully locked out. I'm not worried about them anyways, they did help control the torque curve, but just another thing to go wrong. Phasers are notoriously problematic on 3v engines.

    What would YOU do for an engine build in my situation?

    So would I be better off just getting the heads ported while keeping the original size valves? I really don't want to bore this block more than .020 over. I did see some badazz wet sleeves for a 5.3 stroker setup the other day on YT. I think his bore was 3.700 if I'm remembering correctly...

    What would YOU do for an engine build in my situation?

    For anyone interested in the build, I have decided on a crank. Thanks to another member commenting on another post pointing out the max safe rpm of each stroke available (assuming 5,000ft per min is a safe piston speed). I'm gonna go with the MMR 4.75 crank. It's affordable and comes with a...

    What would YOU do for an engine build in my situation?

    I was comparing it to the 4.6 4v. When someone says "4v" , they're usually talking about a mod motor. Coyote is technically a mod motor, but not really. Anyways, this is how the 3v lines up against the NA 4v mod motors according to Wikipedia 05 - 09 Mustang GT = 300hp / 320lb-ft 93 - 98 Mark...

    What would YOU do for an engine build in my situation?

    If ya don't like it or can't contribute any meaningful info to help with the build, keep scrolling. I get it, it's no secret that it'd be easier on the wallet to go coyote over any mod motor when going for a high horsepower build. That's such an outdated way of looking at things though. I'm...

    What would YOU do for an engine build in my situation?

    Also, just checked my email and Jesel got back to me. There is no rpm or spring rate limits on the followers. Surely there is an actual breaking point, but it must be very high. They're 139 usd each and their lash adjusters are 58 each. He said there would be a 3-4 week build time on them and...

    What would YOU do for an engine build in my situation?

    That is a beautiful car! Love that blower sound. What did you do for rods, pistons, and crank? I'm assuming a huge chunk of that 70k was labor cost? Hopefully I won't be anywhere near that doing everything myself. Hmm, I didn't know that. I'll look into it, I definitely don't wanna be under...

    How to build a proper 4.6 stroker

    Hey guys, so I'm in the middle of a 4.6 3v build and need suggestions on a rotating assembly. The goal is to make 650whp on pump 93 with the ability to go 850whp on e85. It's gonna be a big single turbo (88mm) setup, so I'd like to stroke it for the extra low end power for when I'm not in...

    What would YOU do for an engine build in my situation?

    Ideally, 30k miles would be a realistic goal for 650whp. And I'm only asking for advice on what to use, I'm no engine builder but I have been soaking in every bit of knowledge I can in preparation. I really want to do this right and do plan on measuring everything and taking note. I still need...

    What would YOU do for an engine build in my situation?

    That's why I'm paying for the best of the best 3v followers and lash adjusters. That means absolutely zero and they could easily be worse than stock, but Jesel is a big name for rocker arms and so on.

    What would YOU do for an engine build in my situation?

    Sometimes I wish I'd been a poser, would've been alot cheaper lol. But since you asked, I'll post a Pic or two. You've probably seen it posted on FB in a couple groups, been gathering parts and getting a plan on the build for months now. I've asked as much as possible everywhere I could to help...

    What would YOU do for an engine build in my situation?

    Yeah, I do understand that rpm with an even bigger stroke will be a bit iffy at best. But that's why I'm posting here and asking for help/advice. Do you happen to know the stroke of a coyote? I see them running 8k alot on YT and TikTok, so if I can mirror that rotating assembly without such a...

    MAF and Fuel Trims Wisdom Needed

    What would you suggest for a custom setup? I'll be using a built 3v in a new edge chassis on the stock 03 gt ecu. I already know the maf is different, so I can swap in the slot style that the s197 has. I'm just not sure if my ecu will like it. I'm also in the process of learning HP Tuners and...

    Disappointing dyno run after cam install

    Well actually, underdrive pulleys seem to be useless. Mustang Lifestyle on YT has a car they call Turdzilla they tried them on. It's an 03 mustang gt with a FBO Brenspeed 3v dropped in it. Think he actually lost power with underdrive pulleys. He done a vid on installing them alone and dyno runs...
