Default Buick 455

I am starting to build a 455 and was wondering if anyone has any combinations that are good for the street or anything I might need to know before I start buying parts

Stole this from www.hotrodders.com

Do you know what year of the car that the engine came out of and what car? The 70-73 are the preferred engines but the 74-76 had a thicker cylinder wall but had open chambered heads so the compression ratio was only 7.5-8.5. The numbers are printed on the block just above the #1 cylinder on the deckplane. Those are the best numbers to check. The 455 put out gobs of torque( factory rated at 510 ftlbs.) and were overall small, not too much bigger than a SBC and Weigh about the same. They have 2 bolt main and strong push rods. The bore is 4.31 and the stroke is 3.90. You can ask the guys at V8buicks.com for info on your numbers, it is a forum like this one for buick enthusiasts and TAperformance.com has performance parts for the 455.

I know it is around a 72 to 74. It was a complete motor still has the stock pistons in it. I was going to have it bored .030 and put in forged pistons from TA performance

your block is a good one with larger oil pickup tube. get a oil pump kit(booser plate and hi-volume kit with longer gears) buicks have an aluminum oil pump body. don't scimp on the oil system.Chet Herbert cams has a good cam,, .475"/.500" 218/218.. torque monster. only needs to rev to 5200-5500 rpm. get some sticky tires! 3.42-3.73 gears
