QUESTIONS ASKED ON THE SHOW
when you freshen an engine do you have to use genuine GM parts ??
how much Rpm that a 525 can take with springs?
If I have a crossover header into a Y pipe should I run one inti reversion muffler or two before the Y?
Are you gonna have 602 Beyea Mild steel headers at your show available to buy?
Do y’all have any experience with the Willys fuel pressure regulator? It’s the vacuum actuated one. I haven’t had a chance to call Willy’s and ask them about it, but where does the vacuum hose hook up too?
How much power gain would I see on a 602 by switching my serpentine pulleys system to a cog belt drive system?
Steve do you prefer mufflers on 604 late model if so what type?
602 Header for stop and go tracks, that also get slick in the MidWest…Schoenfelds?
Doing the Rush switch to e85, run a fuel safe cell with the foam not that track matters but run PPMS. How addiment r you that i remove the foam running e85?
Opinions on the Jones front HTD pulleys or the Serpentine pulleys, which is better?
On a 602 is there any performance gain to switch from front to rear on ps pump and fuel pump?
Are there some used crates that where built last year people should stay away from?
What should the average cost be to break-in & dyno a new 602? There are “places” that charge $10k – &12k to “race prep” a 602 without breaking the GM seals. Do plugs, carb, and front pulley setup really justify the cost…if the engine isn’t opened up?
Has Steve received any of the new production Crate engines from GM yet?Is GM catching up at all?
Are flames from a 602 in the corners running 98 a sign of a well tuned engine?
