OK guys in a slightly related line when I do my Chevy 409 stroker build now that Edelbrock has the heads out(Yeah)the car is an auto not a stick and wil look at using a OD. It wil probably be a troque motor like a Pontiac guessing in the 550+ range 700R up to it? Not sure how well a 4L80E would fit in the tunnel of the old X frame.

Skip, I wouldn't hesitate for a moment using one, correctly prepared, of course. Unless you are going to pound the dragstrip every weekend with DOT's, it will be fine. We have quite a few in service behind 454 Chevelle's, and a few Pontiac engines, zero problems or failures to date.......Cliff

No Cliff I will have a 500" Pontiac for track, in a Chevy body. The "little" 470-480 "W" motor will just be "street"
 Check out the new Hot Rod on them.Airflow out of ported E heads is looking pretty good so far, 305 ish on the intake 260 on the exhaust.

I built a 1988 4L60 for a customer back around 2000-2001. He has a 1969 Chevelle with a pretty stout 454 in it. He races it nearly every weekend, and puts a LOT of street miles on it.
He had the engine out about a year ago to be freshened up, so he dropped the transmission off to be checked out. It didn't need anything. I sealed it back up, replaced the 3-4 clutches just because we were in there, and gave it back to him, still going strong. The car runs low 12's in full street trim......Cliff

I think the 4L80E would be a better overall setup, although I have the TH400 and GV setup in my car. |

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.
