Don Terrill’s Speed-Talk

How much overlap is too much for a street motor like this. is 60 degrees too much? How much lobe intensity{is this a real term?} is too much or when does the valve train get noisy? Right now I am looking at a Howards cam ground with their fast ramp hydraulic roller with 269 degrees at .006 and 219 d...

If I was to use a flat top piston with a 70+ CC head, would it be down on power verses the 65 CC head and dished piston? More detonation prone on 93 octane fuel? I am probably going to get an assortment of dual plane manifold and try them on the dyno. Thinking a performer, performer rpm q jet, and a...

Thanks for the continued participation in my post fellas. The cam I am considering is 269/219 hydraulic roller from howards, so real close to the old HE comp cam. Also their seems to be some people who have made a performer RPM Qjet fit iguess I wont know till I try.

Thanks tuner, 1181 Pertronix line along with their coil. Anyone ever use the crane unit and is it still available?

Bill K, I agree as
Forrest Gump would say "one less thing."

Can anyone tell me about the house brand Jeg's or Summit heads? What cross section size and valve size heads do I need, for this build to rev to 5800 to 6000 RPM? What about some cam recommendations for the 3.08 gears and TH400 I will buy whatever converter is needed for it. Do you guys have a favor...

Thanks tuner that is an option just thought the performer would be a worthwhile upgrade, maybe 10 to 20 horsepower above 3500 RPM?

I have the stock dual snorkel air cleaner, I may try to route cold air to the snorkels, also it has the tach drive distributor, which I will rebuild and convert to electronic ignition, any favorites Hays, Pertronix?

No stinger scoops, keeping the Q jet carb, probably a performer intake, RPM range 1800 to 5800. Hasn.t any one ever used a good Q jet great drivability, performance, mileage. I don't, mind spending money on things that need replacing, but buying an edelbrock, holley, weber, or whatever, for this bui...

Autogear that sounds like a fine combination to me, I think you dad is going to really enjoy it, and Cam King is one of the people I hope to speak with before I finalize my combination.

Thank you Gerry P, not sure if I enjoyed your post because you reaffirmed some of my thoughts or the chance to be drunk at sema. Not looking to spend more than required, but not unwilling to purchase what's needed. The 450 HP number is just that a number, I really enjoy driving this car a lot in goo...

Has anyone used a regular performer manifold or any of it's cousins Weiand Holley China etc. to build the kind of power I am looking for?

There probably isn't a problem with the oil ring spacer, but there also may not be any benefit to a 6 inch rod in this engine so it becomes a part I don' need to fuss with.

Thanks for all the suggestions. But I have gone from asking about suggestions for a nice daily driver 383 to now building a dual quad, solid roller cammed engine that will require hood surgery to fit in the car. Does anyone have any first hand experience with the kind of engine I originally asked ab...

I am starting to lean towards the 5.7 rod as well not really interested in the oil ring support spacer either. I will be using the 9000 series cast steel crank not the forged. Only looking for 6000 RPM and 450ish HP and torque. I have the dual snorkle AC, might consider the 73-75 hood with the seale...
