Intakes? Boost? And bears oh my!
Both models do. The later 7545 was the Xcellerator, and the earlier model 7510 both have crossovers. The port size in them directly matches a Felpro 1243 intake gasket. The major difference between the two is it looks like the the 7510 had a slightly larger plenum and didn’t have the raised pad with the Xcellerator emblem.
Here is the early 7510
I will get pictures of the 7545 with detail of the plenum and ports later this evening when I get back home. I especially like the raised floor and tapered runners in these manifolds. I don’t recall what the 7510 is rated for, but Weiand claimed a usable power range of 1500 to 7000 with the 7545.
