Since I'm hot roddin' the 72 a little bit this spring, I'd like to change the intake manifold, while keeping the same height (hood constraints). However, while I'm looking at all the different intakes available, they don't seem to give any more information other then rpm range. Isn't there a more technical way to guage how well an intake manifold works? There are flow numbers for heads, is there anyway to adapt that to an intake? Flow differences between single and dual plane would be nice too. With all the other technical information out there it seems weird that there isn't more for intake manifolds, which seems to be a very common upgrade. If anybody knows anything, I'd be glad to hear it.
Maybe because the lion's share of aftermarket intakes are aluminum, maybe there is more focus on weight reduction then on air/fuel delivery to the heads. If anybody knows or has any opinions I'd like to hear them.
What basically brought this on is I'm trying to decide between the edelbrock performer intake and the ZZ chevrolet intake. The price difference is fairly substantial, so I'd like to compare the specs to see if the ZZ is worth the extra money. The ZZ promises high rise performace in a low rise application, but some numbers to back this up would be ideal. Anybody with practical experience is encouraged to respond.
The stock intake is not that great. The Brodix High Velocity Heads (HVH) 1016 intake will fit under the "flat" small block hood and works quite well in a 4 speed car. I canEmail you photos of 1 I have F.S. ($120 shipped to the 48 states.)
Also, love your car. I'm thinking about putting an LT-1 hood on my car, but that will be several years down the road (have suspension, brakes, bearings, rear end and transmission to go through before I even begin with the body). Gotta love Elkhardt green.
Another thing about that intake...it's a Brodix intake, does that mean I have to have Brodix heads for it to work? I know that their headers and heads work like that. If it does, I'm not planning on using Brodix heads anytime soon, mainly because I want to keep the block and heads together (just finishing the rebuild now).
Since your thinking of going with an Lt-1 hood why not go with a aluminum manifold from an LT-1. The Winters high rise manifold #3959594 has been one of the best flowing manifolds ever made and many manifolds have copied this design, but you'll have to do some shopping to find one and it will not be cheap. With headers and a good carb this is a great way to start with building performance......
