Thank you for the reply Guys ,and Thank you for posting Jim .
I am not at a stage where I can afford to get a new engine ,but more or less trying to see options .
In the future I am not really going to be very happy with 180 HP ,I can see that right now .I don't want a 600HP engine ,or a 7000 rpm screamer , a lumpy cam,or forced to use 4.11 gears ,just enough HP where you don't have to try very hard to peel rubber in first ,and some 2nd gear tire spin would be kinda nice .The car is an auto ,that part sucks ,but I want to keep it stock .
I really want to keep things looking as stock as possible ,
so maybe it would be better to take my 400 I have now ,and someday get the stroker crank and 455 pistons . I guess a person could always paint aluminum heads to have the stock look? I wonder if getting the block to accept 455 pistons would be on the thin side? Or should a person just rebore 30 over and use the next size of 400 pistons, that way keeping the wall thinkness as thick as possible.
I read that people were boring it out further to except 455 pistons ,more or less to same money .I can't see the added cubic inches making a big differance bore wise with the 455 pistons .
Or maybe bite the bullet and build a completely differant engine . I could see a Butler engine build adding up fast . 15 G would probably be just a good start . As you may as well start from the ground up with one of there new block's considering you are getting newer proven technology. Don't know how stock it would look though . You would think the block should look simular enough for the average person off the street not to notice .
But I suspect most people are building Butler engines for 9 second quarter miles lol . Next I'll have to strengthen the frame , tranny,diff ,etc YIKES this is getting out of hand
btw Mr P body ,you are right ,a real Firebird has a Pontiac engine . It pains me to even think of a chevy engine in a T/A
