dont use the cork gaskets that come with the felpro gasket sets. for the front and back of the lower manifold


use a huge ass bead of black RTV silicone. i used the corks and they leaked like crazy.

 

Well we got it finished today, it's pretty straight forward less the 3 point strut bar in the way . That and the guy didn't give us the bolts for the new manifold and no one carries a 5/16 X18 X 6 1/2" long . We had to buy an 8 inch bolt and thread it up higher than factory then trim off the end. We get it all together get the timing reset and all, runs great with ALOT better throttle response and nicer intake sound. One little bump form a thermostat housing gasket tomorrow and it will be back on the road. It still looks funny with the Cobra manifold and the stock intake on there hehe.

 

yes, lowes of all people have those bolts,ive got 2 extra if you need them , they actually have them all the way up to 8.5, they have all different thread lengths, but the 5/16 x 18x 6 1/2 they do have, like .75,i blocked off my coolant and it seems fine.

 

Didn't even realize you asked a question hehe. The 2 center bolts were not long enough.
