Do it or STFU.

Both of you.


You claim, now prove it.
Not possible, started parting the car out about three weeks ago. Probably wouldn't bother if it were possible.

And yes, I did make it personal. You come here to our forums and make big claims about everyone but you not knowing what they are talking about. We have been working with and collaborating on these vehicles for 20 years. As a group we have plenty of experience to share and a strong idea who's talking out their ass, and who's so full of it there eyes are brown. My own build thread is one of the better documented builds in XJ history.

You sir are an ass. We all know it. None of us care.

Guys expect something that is not there, will never be there.
I tried multiple Strokers. I will never do it again. Not worth the uncertainty nor the cost. But I did notice decent feel of the butt power. Dyno was disappointing, but that likely was due to not able to Keep the 32RH in to 2nd gear. kept starting in 1st, and no way to hold in 2nd.

I do know my Aluminum Edelbrock head flowed more than my camelback SBC heads did on many of 68-72 cevelles, el caminos, and firebird I have owned and built over the last 30 years of building cars/jeeps/etc..

As well as from what I have seen, it outflowed many BBC oval port heads that were OE, or even aftermarket untouched... Including most OE and aftermarket SBC head out there.

And so that you dont go crying to momma about all lies....

Theres reference for head flows that I quickly found.
And here is MY head flow...



And what it looked like...


Its the one in red...

Re: 4.6 build starts today!!!

A few of my thoughts to hopefully add some clarity and address some misconceptions.

Ron contacted me and started this thread with the purpose of building a 4.6 stroker based off a late-model coil pack head with the goal of making good low-end torque with a emphasis on reliability and to easily pass smog.

The engine consists of a Scat 3.985 stroke Crankshaft with a set of my steel bushed connecting rods, Bishop-Buehl/RaceTec 4032 forged pistons. The 0331 head is fully ported with stainless Chevy LS valves and springs, Harland Sharp rollers along with a very conservative Comp cam grind. The iIntake is port matched and opened up to except a 62 mm throttlebody.

I spoke with Mike at Lopers Performance today to clarify questions that I had along with giving me some feedback. He said that Ron nailed it with the choice of 27 pound injectors and confirmed that he made a high gear runs that netted 227HP and 396TQ to the rear wheels putting flywheel horse power at just over 300HP without having to go to 4000 RPM.
Mike said with more pulls and trimming the fuel the power and torque would've increased further.

At this point Ron's objectives were met and no more pulls or changes needed to be made.
Ron is still running his stock exhaust pipe, catalytic converter and muffler.

Don't hesitate to call me if anybody has any questions or would like to discuss stroker kit packages

Re: 4.6 build starts today!!!

I'll elaborate on that thought.........knowing that the basic math of the motor means almost nothing.......my original contact with Russ was about his headwork as I had heard so many good things about him. The numbers that were achieved were far from anything I imagined when I started and his professionalism and devotion to each project gets my highest respect.
