Ive bought an AED 1/2" open wooden spacer for my 440 to keep the heat out of my carb. 440, lightly ported aluminum sidewinder heads, eddy rpm intake, eddy 800 thunder avs carb, 1 7/8" exh, 10.5:1 compression, 254@50 duration 554 lift single pattern, 4000 stall, 4.10 dana. 4000lb car.
Im doing a little research on spacers and Im not knowledgeable enough to predict if a 1" tapered spacer (or other size) from wilson will improve my combo or just do the same job as my 1/2" for 4x the price. I would just buy one and try it if it wasnt so expensive.

There's really only one way to know what it will do on your exact combo.

Most running the taper/contoured spacers have said it leans out the mixture to require a carb change/adjustment...........

I'm not sure that a 4 hole merge spacer is going to be the hot ticket sitting on top of a dual plane manifold.......... But it's easy to try.
