N/A build Big Bore Stroker or 5.0 Coyote

I had 127600's in my 4.6. Street ability was fine. It was actually kind of fun when the car idled and your vision would blur from the shaking. LOL

Quick idle video...



Idle with mufflers plus a drive away...

It sounds good, very similar to the 127500 cams in my car now.

Neither of those. I'm building a 2013 NA Cobra Jet so I can go class racing. Stock eliminator rules allow .080 overbore max, putting the sleeves in gives me a .070 overbore. The 2 or 3 NA CJs that Ford built came this way as well.

Is this the motor thats supposed to make 600-700 hp at the crank ?

Yep, but at 12.5:1 with the CJ cams, Boss 302 heads, SCJ Throttle Body, CJ IM, 123mm MAF housing, CJ oil Pump, CJ Pulse Ring, Forged Manley Rods, Forged Mahle graphal pistons, 12qt. oil pan, underdrive alternator pulley.

I still think you should go and just buy a 5.0 instead of dealing with the hassle of trying to put one into your car or trying to go all out with a Big Bore Stroker while not being able to reach your goals. Hell a 5.0 with a 2010 JLT CAI, JPC LT's CJ IM, and SCJ TB made 465/423 STD 452/411 SAE on E85 and 482/445 STD 468/433 SAE on FTW. THey say that the JLT was a restriction of about 10HP when switched to a 4.5" CAI, no idea what intake tube that was though. It just seems so much easier to meet your goals with a 5.0 instead of trying to go the Big Bore Stroker route. I'm not sure what you have other than the 127500's but you are looking at, at least 12k in parts assuming you have the heads and cams already.

What would be the highest compression that someone could get on a big bore stroker? A part of me is thinking about ditching the turbo kit and doing a high cr bb stroker with heads, cams, etc. I have the built motor I have now I could sell along with the turbo kit to fund the project.

This will help with the cr. http://www.wallaceracing.com/cr_test2.php

It get's pretty hard to go more than 12:1. A set of stage 3 heads with the 48cc combustion chamber would really help.

Well the car is paid off, really don't want a car payment for awhile. As far as what components I have now, they are the cams, springs, phasers, frpp im, tb. The bb stroker shortblock will cost 5,000, headwork 2,500, bb head gasket kit, motor mt plates and misc. maybe another 1, 000. So about 8,500 to stay 3 V. I really like the idea of a Coyote conversion.

^Damn if it would really cost that much I will just keep my 285ci 700rwhp setup I have now. I only have about 3k in the engine I have now.
