Thinking of building a 400 E block motor with Edelbrock performance heads need advice on the cam want something big and lumpy bottom end will be stock bore and balanced also it will be going into a stick car

 

Suggest you reach out to member 'cutlassefi'. He can suggest (and supply) a really good cam for your application. He can also provide guidance on any and all of the other parts you may need for your build.

 

X2. Can't say enough good things about Mark.

 

Find out what cam bank angle block you have. I think '65 is 45 degrees, '66-67 is 39 degrees. The 400E is the better "400 engine" to build for performance.

 

You’re making me blush😎
I try, thanks gentlemen.
Op- you mentioned std bore, I’m guessing then that you’re not touching the bottom end?
If not then we’ll have to work with the stock comp ratio. Is it the 10+:1 version? That will dictate the cam choice to a great degree.
Thanks.

 

ya don't want to touch bottom end and yes 10+:1 looking for a nice lumpy cam kinda like a w30 cam but bigger

 

1965 400 is a B block, 45° camshaft. E block is 1966/1967. Seeing as how your going aluminium heads would you be interested in a 425 D of a 455 F block/engine trade? If you want to discuss it PM me. Ken

 

I already have a 455 and no don't want to trade the E block is going into my 68 w30 so I can beat the hell out of it and enjoy the high rpm' and store my original engine

 

Thank you, I am better informed.

 

FYI- That has little to nothing to do with the displacement. My dyno guy does 858ci mountain builds that rev to 8800rpm.
If it’s a 39 degree block then you’ll be fine with the Edelbrocks. But if it’s a 45 then you’ll need to machine the pushrod guide holes.
I’d do 232/240@.050 on a 108 Erson. Lift is in the .560 range to best use a good cyl Head.
Hope this helps.

 

I've got 1967 D block C headed 425, 39° cammed, similar to E engine but 25 cubic inches larger, same forged crankshaft, rods. Either way if engine is seeking high rpms you should get better connecting rods. Mark can fill you in on a better 7 inch rods already sized for Olds or machine crank for a better selection of rods. If you are making a "high" winder that's the way to go. Kind of like opening a can of worms.
