Hey guys, been a while since I've posted. I know I'm prolly gonna get flamed on this one but I've built a 454 for my sons 95 ECSB OBS. I've got pretty much everything done except for paint and transmission. I will prolly have a lot of questions as I try to fire this thing up and especially when I go to dial it in.
Here are some specs:
Standard bore 94 genV block
Flat top stock pistons
100cc 96 vortec heads, steel roller rockers and springs for cam
9-1 compression
Lunati 60203 cam, maybe a touch to much
.542 in .554 ex. Dur 227 233 @ .050"
Holley tbi, MSD dist, dynomax shorty headers

Thinking between 400 to 450 HP
Question for now is which fuel pump? I was thinking of going with 96 up vortec truck pump after talking with the manufacturer (airtek). Next concern is the break in. Should I just throw a Holley I've got on it for that or can I start off with a base tune close enough to not blow this thing in the first twenty minutes of it life?
Thanks for reading this and I look forward to your responses.
Chris.
