Don Terrill’s Speed-Talk

Yes Greg, and he's agreed to build them...thank you!

Lemons does not do Ford or any custom headers anymore.

Looking for any info of existing or someone who can build Headers or modify headers for a 67 mustang, 9.5 deck and Blue Thunder 3.6 heads...I already have flanges for the heads.
I'm in So. Cali but can travel if need be.

Thank you!

Looking for a decent cnc program out there for this head, NA build.
Thank you!

Well if they can't get that right...what says there aren't other hidden problems? He won't hold me responsible, but you and I know that if I assemble it and it fails, he won't be happy. I just don't understand the reasoning behind it.

A customer I've known for a while bought a bunch of engine parts over the covid shutdown and brought them to me for assembly...speedmaster sbc block... :cry: So looking it over, I see the feed hole in the rear main cap...it's maybe .350-.375 in diameter! WTF??? I don't think I'm going to assemble th...

if you don't like the pressure, just use a different spring combo for break in...single spring with 250 or so open psi.

Planning to build a 440 stroker in the 550hp range, but don't have much BBM experience. Going in a 1970 B-Body. 3-spd auto. Mostly street car, some highway cruises, occasional visit to the strip, want it to run on 91 octane and have good enough vacuum for brakes and possible fuel injection. Will ha...

Ultradyne was known for wanting 6° of advance in most of their grinds...so that may be why your friend told you that?

His lobes can have quite a large amount of asymmetry so it's best to check them using the lobe center line method and check .020 before and after max lift to find true center line.

"Looking at the jesel belt the timkng pointer reads -2 degrees. Now I know whithout a degree wheel that doesnt mean much but cam card wants cam on a 111 ICL. If this is 6 degrees retarded, will that give me some of my issues?"

Are you saying the cam was NOT degreed in?

I like the SCE pan gaskets...1PC rear main seal from Felpro...use the Flueromaster seal.

We used Isky's 221-232@ .050 cam, .543-.560 lift on a 114lca. Stock semi closed chamber heads, just typical 3 angle style valve job, back cut both intake and exhaust valves due to wide lobe center cam. Flat top pistons, zero decked, 6.385 rod, rpm intake and Edelbrocks new AVS 2 800 cfm carb. Accell...

Do some chamber work to lower the comp down to 9.6:1. We just did a 496 with semi closed chambers, flat tops...9.6:1, no port work, hyd. Isky cam and rpm intake...made 472HP and 548TQ. Cam is small 221@ .050.
