Edelbrock heads ?? #642610 03/17/10 01:30 AM 03/17/10 01:30 AM

I have a set of Eddie's laying around and I am thinking of throwing them on my 440. Here is a short spec list, trw 2295's, 304/272@50-555" solid cam, and basic oiling system. The 915's had stock sized stainless valves and were basically cleaned up and gasket matched. I ran it with an M1 intake and a 950hp holley. What gain do you potentially see from the edelbrocks? I also have a victor I could put on as well. All opinions welcome

As far as I know an out of the box Rpm head will make similar power to a ported factory iron head. Bolt em on ! Depending on the car combo, even the lower $ Eddy Rpm's or 440 source heads can go REAL quick at the track.

Be advised that the L2295F piston has a small dome with a centralized spark plug relief, and the Eddys have angled spark plugs that might contact the dome. I have never checked for this, but you should. Even a Ross domed piston has to be relieved to clear an Indy head's angled plugs... RB

(Mine is a 440-port motor, not a Max Wedge deal). I'm an aluminum fan when it comes to heads, for weight, port-work & repairability. I use the FelPro composite (1009?) gaskets, not metal, and run double springs.

Bill I think in the beginning, they were hyping flow numbers in the magazine ads of 290-something. I've had three sets on two different benches that were no where close to that... But to Johhny's question, they should be a gain over all but the most advanced OEM head... Last edited by cudadoug; 03/17/10 05:08 PM.

Looking at them, I only see the weight,angle plug and smaller valve stem size as a benefit. The ports are far from impressive I will bolt them on and see what happens. If it's a turd I will spray the life into it Bill, I have all the 470 parts together now, just need to get the block work done.I plan on stuffing that in sometime this fall. This engine will be my backup junker. Just want to go play untill then

Not 255cfm that Eddy says. I called the tech line and their response is that their numbers are accurate to 10% and that they use a 4.125 bore. That means they take the real number and inflate it 10%. I was really disappointed with the outcome. My J heads flow 255 and to put the eddys on would probably go slower. 68 twin turbo Dart 8.19 so far 70 Swinger 360 69 Roadrunner 383 4 speed 69 Mod Top Satellite 383 auto 69.5 A12 Super Bee 4 speed 70 T/A Challenger 70 FC7 Duster 340 4 speed 70 FJ5 Superbird 68 Hemi 4 speed Roadrunner 71 Duster W2 340

Or...to be fair to Edelbrock, maybe they used the bench at Westech...
