SNIPER EFI Quadrajet on a 455 Pontiac ?
I'm considering installing the sniper spreadbore EFI on my iron manifold on a 469 pontiac. The engine has a 236/242 @50 roller cam and makes 500hp/577tq with its holley 800 spreadbore. On the engine dyno, the hat said the engine was only using about 650 cfm of air. The Sniper spreadbore is rated at 715 crm. While the EFI is rated for 500hp, do yall think 715 cfm flows enough to support similar hp figures the 800 holley spreadbore made?
