One with the basic GT40 heads, I trust the guy selling it. Low mileage engine to replace my tired and worn out 25 year old long block. Do you guys think the power levels will increase some with the E6 vs GT40 heads and tired vs "newer"?

My main question is, would I need another tune. Are there things I should know about such as compression ratio differences? Mods going to this engine:

Novi1220 @ 6 pounds only
GT40 tubular intake
75mm TB + MAF
Shorty headers

I'm thinking about getting an aftermarket cam, although that's debatable for now. And I don't know where to start and what's needed to take advantage of the blower and such...

Thanks

I still would crack it open to put new bearings and rings in it. You shouldnt need a tune but wouldnt hurt and that block is almost no different than the one you have. Why not rebuild the one that you have already? Since your going through all the trouble...
