New Motor

[BillD]

OK, Thanks for the help. I was actually thinking that I could sell what was in there and go with a crate type motor and end up ahead of the game both on $ and performance. I think Mark put the disadvantages of that plan in very good perspective.

Bill, the only thing you might consider is using some oval port heads instead of the 840's. For a street driven car the low end torque is much better. A good set of oval ports with a professional valve job will really make the motor fun. Keep the compression reasonable so you can utilize pump gas. You didn't say anyhing about what cam you have or might use on the rebuild. Lots of good stuff out there today depending on your budget. If you like solids, the L78 "163" unit is hard to beat. Good luck.

Ps let me know if you need some oval port heads, I have a couple of sets in the shop.

I would sell what you have. Buy the crate motor and pocket the diff.

And I'll bet you know someone who would buy all that "Old Stuff".

(Like you need any more.............. )

Why take the chance of blowing up a 512 block and 840 heads. Just go buy a 454 build it up with oval ports. My gibb nova was a oval port 427. 500 hp on the dyno. PS I have 40 big blocks laying around now. I don't need anymore.
