Re: Pontiac 400
thanks curtis, I will have to take a good look into it I guess. the issue is that this firebird is my only car so to put it on hold for any long period of time is difficult.
I am not mechanically inclined enough to rebuild the motor on my own. But i can assemble assemble certain parts of the motor. I put together the heads on the current motor. I agree that the 403 has potential but it also has a fair few flaws... At least thats what i have found during the last 4 builds gone wrong. Maybe i need to find a better builder or something.
The heads are no issue I found though cause the 350 rockets type 7's fit (you need to enlarge the head bolts to fit the 403 block though) And the 455 sized valves fit in with a bit of work.
Still this altitude drives me nuts I cannot make the thing ping for the life of me. I was able to get it to ping once in texas...
Well then i wont do anything for awhile, have been able to find flatops for this motor? christ they are nowhere.
well its the middle of the night and im tired ill write back soon thanks again for all your help
