I just got my 455 back from the machine shop and I want to get some opinions on it before I start to build it.
Here is what I have: 455 bored .040 over (465 CI) '46' heads with a 3 angle valve job, comp 995 dual valve spring, stock rockers and with roughly 9.7:1 CR CC XE274 cam and hyd. lifters Reconditioned stock rods with ARP bolts and KB pistons Stock crank, grinded and indexed. Edelbrock Performer intake Edelbrock 750cfm electric choke I have a TH350 with a 2200 stall and 3.08 in the rear. Also any HP guesses or 1/4 times?

With the tune dialed-in and adequate traction, it should be capable of solid mid-12's. That is, of course, "corrected to sea-level" times!
I've seen some slightly milder combos run low-12's, with some really good tuning & driving. I'm guessing that you'll use some good headers & exhaust system. Lee

Thanks for the response Lee. I forgot to mention I'm running Doug's coated headers and have the Pypes 2.5" X system.
67gtocpe: Hey it's nice to see another Utahn on here. Too bad my car is down in Spanish Fork or you could see it (if it ran). I work up on the Army reserve center up in Ogden. Maybe I could stop by sometime and check out your car. I'm still an extreme beginner so maybe you could teach me the Pontiac ways.  Morty4@hotmail.com

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
