I've seen A LOT of posts about making HP with a 318-So why is it so ???

There's a warmed up 56 331 Hemi five feet away from it. I've thought about it. Here's the plan. The 170 and three speed comes out. 170 on the stand to get a Weber 32/36 and bored out exhaust manifold and a basic valve job and a new timing set and the whole thing gets resealed.

While it's out, the 400 gets mocked up with heads and exhaust manifolds and lowered in place "to see" how bad "it won't fit". Lots of pictures taken. Then when I figure out if the three on the tree can stay, the slant goes back in with 2 1/2" upgraded exhaust all resealed up with new timing set and a snappy little Weber. Even if I leave the 170 in at that point (and it's very likely I will) I will have new information for those want to big block swap an early A body. And if for some reason I decide to big block the car, I'll go ahead and hang the Ford 9" under the car and do it. I might. You never know. I also still have my long rod 225 build going on too, so "there's THAT". lol

How about a 8" Grabber rear end with 4.62 gears and a mini-spool?? :)
