Anybody got any experience of using this kit (SUM G5212)?
How did it work out? Which springs did you use?

I am just starting to tune my 1977 350 in my 91RS. The crane vacuum can will be installed tomorrow.
Any advice?

Thanks for any reply.
Andy.

 

I haven't tried theirs. The Mr. Gasket HEI sets I've had in the past I only used the springs out of it. The weights/center plate were worthless.

Wouldn't surprise me if Summit & Mr. Gasket are the same thing. But, I don't know that for certain.

 

Basicly the same as all the curve kits, specture $8 parts store or mr gasket $12 and what ever the summit kit costs.
You can run down to any parts store for the kit they all stock them. I personally have used the weights because my old ones were worn badly but the stock ones work fine. As far as the springs (important part of the kit) it just depends on engine setup. Ive used the lightest ones and a mix of either L or M.
