I’m upgrading to a 600cfm Edelbrock 1409 carb on my boat from the stock 2bbl. It’s a ‘99 305 Vortec. My first choice for intake manifold is the Edelbrock 2716 RPM Performer. However a local guy is selling a GM 12366573 Performer-style intake pretty cheap, probably a new take-off from a crate engine. As far as I can tell the only differences between the two are the the GM intake is almost an inch taller. But I haven’t located an ideal operating range for that manifold. Since my ideal operating range is idle-5500rpm, will the GM manifold adversely affect my holeshot, or do you think the difference will be negligible on a stock motor?
