Re: power valve and jets
 

Well, I switched over to a PV plug and rejetted (82s) my L78 this afternoon. Drove to a cruise tonite, and, on the way home, did some light to light testing against my friend in his 1969 350/350 vette. My car pulled extremely strong. Got home and pulled one plug, looked great. I'll probably wait a couple of weeks before completely endorsing this setup. Thnaks all for the info.

How's 3rd gear? That's where I noticed the biggest change when I went to the 'plug' - it pull's like monster truck, just keep the tires under it https://www.yenko.net/ubbthreads/imag...mlins/grin.gif

My car has a TH 400, and 2nd and 3rd pulled real hard. I didn't have the room to let 3rd gear go too long. But so far I ike the way its running.
