351 c intake on a 400 block

I am using this set up on 417 , I found that the heads with the Roush stuffers would ET slower than ported heads with out the stuffers . i do a gree that the spacers could be thicker to aline the ports better .What are you using for heads and pistons ? i am using 1971 heads and flat top K / B cleveland pistons with reworked 400 rods bushed to .912 small end. this gives me about 12,7 compression. Maybe the roush stuffers work better with lower compression. Do you find this valuable?

since the difference in decks is 1.1 in. you'll need a spacer height of 1.25 or greater depending on actual block hgt. with the help of a jig or dummy block setup ( and access to a mig welder) the proper intake for your needs can be built , whether carb(s) or e.f.i. your runner lengthis vital to engine performance!!

You will get a lot more response because the traffic is 10 times this WIKI, besides that, I don't have time/expertise to moderate this forum.
Thank You.
