Officially throwing in the towel on the edelbrock performer rpm intake,just more hassle than its worth to me. Any suggestions for an intake that will fit under the air grabber hood and come close to working with factory throttle and kickdown linkages yet still deliver solid performance. It's going on a 512 stroker with 440 source stealth heads, Comp cam part # 23-229-4 hyd flat tappet .564 lift int and exh, 295 duration int, 307 duration exh. Looking at the Holley street dominator but hoping some of you guys that have forgot more than I know will chime in with some advice. Also using edelbrock performer 800 cfm carb

 

The holley dominator intake is lower than the RPM performer intake. I bought one for a standby if my RPM performer wasn't going to fit in my 69 gtx

 

Call Holley and ask them how much higher theirs is versus stock.

 

i'm using a holley street dominator on my low deck & from the reading i've been doing there's not much in it at all concerning power numbers to the other good inlet manifolds . & there not as high "but" i don't think they make them anymore . as a side note we made alot more power using carb spacers , 3" then cut a hole in the hood . this may help we had to use a cable linkage set up called lock something . i'll go have a look . lockar is the brand . try that mate .

 

Holley Street Dominator single plane manifold with fit and "clear"
and,
it makes MORE power than the Performer RPM.
