Re: Edelbrock Marine Heads
 

Still looking for flow numbers on these heads. Anybody?????

Re: Edelbrock Marine Heads
 

Bigwavz, I have the flow figures for the Edelbrock 454-R heads. I believe these are the same basic castings as the marine heads. Send me an e-mail or pm if you would like these figures.

Re: Edelbrock Marine Heads
 

I have the 7760 edelbrocks on a 540 that makes 570 Hp and 600 TQ with 8.5 compression. They have some port matching done and that's it.

Re: Edelbrock Marine Heads
 

For what it's worth I called Edelbrock and they stated that on a bone stock 502 MPI that the heads would give you an additional 40 HP at 5000 RPM. Not bad for a bolt on with the good valves. Everything else transfers from your stock cast iron heads such as rockers etc.

Re: Edelbrock Marine Heads
 

I think you'll see that the Iron Eagles from Competition Products with inconel upgrade for ~$1600 will flow substantially better and should generate better heat for power.
Just a thought...

Nordic heat--

You may be right about the flow, but the last thing I want is hotter cylinder temps. You must have not read my earlier posts. I am running blown 502's and I need to have cooler cyl temps. That is why I am going with aluminum, plus they can be easily repaired if damaged.

Sorry, missed that one :rolleyes:
That being the case be warned that the decks on the Edelbrocks are not the thickest and you could have heasd gasket issues. I know first hand :(

Re: Edelbrock Marine Heads
 

Bigwavz,
You'd be better off to get hold of RM builder and get a set of Canfields complete with all the parts ready to go. Thicker decks and killer flow numbers. You will need new head bolts.

Guys--

Unfortunately I have a limited budget :( I am doing both motors and for 1300.00 a pair I think they are a good deal. I thought the Edelbrocks have thick decks?? I am also going with head studs from ARP :D :D If some one knows of a better aluminum head for no more than 1500.00/pair including Inconel valves then I'm a buyer :D

Thanks

Howdy there, I just bolted on a pair of Edlebrock Oval port Marine heads on my Gen 6 and installed a 502/502 GM cam. I have Crane Gold Roller Rockers ready to go but am having a heck of a time measuring for new pushrods. Does anyone have this configuration and or any ideas on what length they would be. Thanks, TR
