I am not a gear head like most in here who build most if not all of their cars. I have found a good car and engine builder who gives me great advice and options on the different ways to go. After a year or longer on contemplating on what to do with my engine my builder and I came up with a plan to le Butler Performance help me out.(since Butler is an hour or so away from me). I have owned my '69 Firebird for the past 25+ years and my main concern was not to damage the original engine. The OD on my car reads 30,000 miles pluse. I always thought it was a 130,000 mile car by my builder says it is a 30,000 mile car (by looking at certain parts taken off my car.)
The 455ci sounds good to me. I know the 455ci is probably all I need but adding a few more ci's is only a few dollars away. And yes, with more ci's I will need to step up the trany (which I already have), rear end (probably GM 12), and suspension.
I don't plan on racing the car at the track but having fun with it on nice, sunny, dry days. But if a Camaro drives up beside me I may "flog it" alittle while smiling ear to ear.
Do you think the 455ci (with upgrades) is all I need?
