i have an opurtunity to purchase a a dominator strip intake manifold but the owner of it doesnt know if it is a sbc or bbc are there any way of telling them apart bolt patterns or distributor location stuff like that ? thanks

A holley strip dominator is a pretty wild intak for a street
car. Unless you're going big cam, high compression all out street racer , it a bad choice.

All holley manifolds have a part number cast on the manifold. Get the number off the manifold and look it up online.

i have a rebuilt 76 chevy 350 with suffix head number #882 they have the 1.94/1.50 valves 1.5 rockers stock pistons and crank.i have headers..i need a intake manifold,carburetor ,and cam... In your opinon what setup do i need to reach 350 horse power ?.do you have any cam recommendations? i'm lost in all the numbers? its for street use but i want raw power availiable..thanks

i also have 550 valve springs

Trash the heads (could be argued they're already trash). With stock pistons, which are probably dished, you want no more than 64cc chambers (882's are 76cc), could even go with 305 heads and their 58cc chambers. World S/R Torquers or Pro Topline aftermarket heads would be good choices, or some L98 083 casting heads. 2.02 intake and 1.60 exhaust valves are typical performance sizes for a 350, but 1.94/1.50 will support the power you're shootin' at.

Comp XE268 cam, or something like it.

Weiand Action+ or Stealth intake manifold. Holley or Demon 650 or 750 CFM carb.

i know this is way of the carburetor subject but is the LS1 suffix #306 a good head? thanks
