^yup. My buddy is at 530 rwhp or so on a stock block 3v and its lived for 3 years although it doesnt see a lot of miles either
I think we need to pay BruceH to post up all the parts on exactly how he would do the "solid budget build" lol. From what I've gathered so far it would likely be an iron block, stock crank, boss rods and he said don't skimp in the bearings and such! I'd be interested in seeing a parts list if he was up to it though lol
Why pay money for a block? Everything else I agree with. I would shoot for at least 10.5:1 as far as piston choice goes. Other than that I think any manufacturer would be fine.
FYI Manley rates their h beams at 700 hp. Not rwhp. The boss rods are beefier than stock but there is no way they are as strong as a hbeam with arp2000 bolts.
What are people pushing the boss rods to? Here's a pic of a generic h beam next to a boss rod. Just as a guesstimation I'd think the boss rods could handle as much as a gt500 stock rod. The reason I say that is because they look very similar, are made the same way with the same material, and the boss rods should be stronger due to being shorter.
I think a lot of you are looking at this from the bottom up rather than the top down.
On a blown car the blower makes the power. Period. It is what is “metering” the air going into the motor. And the amount of air in the motor defines how much power it makes (add fuel, make go boom). When comparing a 3v to a Coyote (lets assume at the same compression ration) the only real difference is the head flow. So, they will make the same power, but the 3v will have higher boost. Same amount of air, different resistance.
Now if you are trying to build a max effort pump gas motor the Coyote would be the way to go. It will make more power on less boost and let you run 93 octane at a higher HP. How much HP I don’t know, it’s not like the Coyote heads flow THAT much more than the 3v stuff does. My wild ass guess 50-75hp.
If you are going to run e85 or race fuel it starts to not matter as much anymore because a couple pounds of boost extra (on the 3v) will be taken care of by the fuel.
Now if your going to build a max effort motor and go for 800+hp you are certainly dealing with e85 or race fuel and big blower. So head flow, where it is nice is not at the top of the priority list. Don’t forget the 3v heads flow big block type numbers. Top priority is keeping the bottom end together. And this is where the Coyote has a shortcoming. Without extensive block mods (expensive) you will split the block. The 3v block on the other hand, or better yet aluminum or iron Teksid blocks or a BOSS iron block will hold up to whatever you can throw its way. I’ve heard of stock 3v blocks living in the 1300+hp range.
Money no object I would build a Coyote for a max effort. But I don’t see myself being in a “money no object” situation anytime soon.
