Ok now i have seen a wieland x-Celerator intake in summit for a 351 c with 2 or 4v heads now i was wondering first if the 2v or 4v version would fit aussie heads (i think is 2v, but im not sure) and second will it clear a stock 67 hood? and will it have a good effetc on hp?

 

oh and i forgot to add i have a 600 holley on there right now, and a 10" edelbrock filter if it makes much diff

 

aussie are 2v heads with closed chambers for compression bump over standard 2v heads with open chambers.

yes it will fut under the hood but you might need to invest in a drop base filter

You have not supplied enough information to answer a power question, however, if you are simply bolting an open plenum intake onto an otherwise stock motor with aussie heads, you might not be happy. Need to know the whole drivetrain combination.

 

ok well im building the motor and its gunna have .030 boreover forged pistons, obviously the aussie heads, a 600 holley (right now may bump it up later) probably gear drive timing, scorpion roller rockers, hydraulic lifters witha street strip cam, comp cam lifter and cam, and drivetrain is toploader 4spd, and 4:11 gears, but will be 3:56 or so when im done,
