Whats the pros/cons of phenolic spacer vs thick gasket to combat fuel percolation on a small block?
Phenolic spacers can be had in any size.
Will need 2 base gaskets to use.
Can create issues with linkage.
Can create hood clearance issues if you don't pick the right size.
Work well at keeping the carb cooler.
Can warp.
Edelbrock 9266 or 9265 Heat Insulator Gasket
Comes in one height.
Doesn't need base gaskets.
No issues with linkage.
No issues with hood clearance. (Drop down air-filter).
Work well at keeping the carb cooler.
Will never warp.
My go to !!!!!
If you are running an Edelbrock carb, get the Edelbrock heat insulator gasket. You will never look back.
And yes, they are reusable.
Thanks, would you go open or 4 hole with the LD4B?
I don't know if the gasket helps, or not. I'll wait for others input.
If you have the room under the hood, I would play with a spacer. I have seen them make horsepower for almost no money.
I think the spacers that seem to work (ENTIRELY dependent on engine combo) is a four hole on a single plane intake, and an open spacer on a dual plane.
Tuning for the spacer may be required.
My thinking is "stacking" multiple pieces raises the risk of leaks.
Thanks
We had one on before, not sure what happened to it, but I do know we swapped carbs so I may have tossed it and it seemed to work.
Are they reusable?
I called the local "speed shop" to see if they had one......said phenolic spacer is better. I take the half hour drive in, and he showed me spacer. I said nope, the bolt holes are too wide(I want eddy inner bolt pattern). He said nope yours has been modified or it's an AFB. I said well technically your right, an AFB is on it now, BUT I just did a carb swap.....Eddy 1405>Carter 4295S. He said "nope AFB to Eddy are different, not gonna argue with you" Those were his words...oh he then mentioned Vic Edlebrock....blah blah blah and they're shitty carbs lol. Moron, no wonder his shelves/products are covered in dust. Douche...
The Eddy gasket is like $75 up here, CRAZY.
Yep no gaskets with Eddy, but a "spacer" of any other kind requires 2 gaskets correct?
I've never had heat percolation Steve...if you do it might be because your timing is too retarded and their is too much fire in your heads and exhaust instead of the cylinders?
See if your headers are red in the dark.
