Magiver-
If not the thermo... Toss me some ideas on my HP 360 intake. Or even w replacing the intake too.

Thanks!

Btw I just got car and going through what's here. First mopar... First engine build
As above... Got the HP 360 manifold and a Carter Chevy 4bbl on an adapter. I believe all else to be stock....

I'm assuming that HP 360 is a cast iron 360 four barrel intake manifold? If this is correct your probably looking at a slight miss match (bigger 360 intake runner going into smaller 318 heads? ) I personally was able to find a edelbrock 318 street master at a swap meet for $ 80 . I also found a nice rebuilt 600 Holley for $ 120. It was a great combination. I had a edelbrock 600 cfm on the last 318 and was happy with it also.

Like I've been told, and also recommend- make a good plan and STAY WITH IT.

MHO-- recap--( spent a lot of money unnecessarily to get to this) 600 cfm edelbrock / holley, used aftermarket four barrel intake manifold, as big as a cam you are willing to deal with? (That's the hard decision! ), cheep summit headers ( I tried used headers and they leaked, never again, and a B & M stage 2 shift kit ( the shift kit was scary, but I followed the instructions and it turned out great)
I couldn't agree more on not using old cam or lifters just not worth it. At least get your cam re-ground with new lifters if not a new cam and lifters.
