Don Terrill’s Speed-Talk

Observations from a hobbyists point of view; The flow curve shows possible intake port stability/air speed problems at higher lifts, where the port energy also drops like a tail. Heres one head im working on that i expect will help the car out of corners and also have good top speed. (igonore the e...

I suppose your not allowed to use the W shaped or finned intake port floor. Would be a cool way to have fun with the port while complying with the cc rules. You can.. I tried it on my first engine. "I tried it on my first engine." did it gain HP ?? did it lose HP ??? or no difference in H...

You can.. I tried it on my first engine.

So Larry I know you will appreciate this. This would be the Edelbrock that would replace the 041. This set is for a 350/300hp combo.

While I appreciate the purest, the aluminum head is bigger in volume to be legal.

Chad,did you or were you allowed to use open spacers on this?

Yes we tried several.

Had to laugh. Working on a set of Indy AMC heads. The shape totally reminds me of a 23º Chevy.

Yea.. no words needed.

He just won class as the Baby Gators today!

Customer just texted and I did a Super Stock manifold for him. This manifold. Said it's worth .06! NICE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
MIGHT HAVE PICKED UP ANOTHER .04 SMOOTH! HA!

I can add that when I ordered my new CP pistons for the Super Stock engine, the first call was to the expert (no names) at Total Seal on what is the best rings to build the piston to. Long story short it's a $220 .7/.7/2mm set of rings.

I was responding to Speier about his car.

I got it as low as I could. Still has a 16" cam center. But I have to add weight so I will get it ironed out.
