SS/SBC 1970 350/360 or 370

[Dragsinger]

Racers,

I am considering building a SS/GT with the 350/360or370. I like that combo because of the Holley carb, dome piston, and bigger valves. [all good things].

*The Car would be my 1982 Camaro Lamplighter because it will take only a few minor changes to make that body legal. Plus, they are proven, performers.

Questions:

*The specs I see are mostly the same for the 360 or 370 engine, so I expect the 360 factored to whatever is the best choice.

*A number of the classic SBC heads are legal. Does any casting hold any advantage? The heads with the bolt holes on end are convenient. I intend to use OE castings, not aftermarket.

*I am open to any experience or thoughts.

Thanks, Larry Woodfin

Good morning Larry,
From my past experience the 1.94/1.50 #186 Chevrolet castings are a very good starting point, as long as they aren't cracked! They can be upgraded to the 2.02 / 1.60 valves and then you're starting with the valve seats in fresh metal. The #186 castings I've found to be the best flowing factory heads for a Small Block Chevy (with the small chambers). I would suggest that you give Glenn @ B&B Auto machine a call if you need further information.
Good luck with you're build.

Respectfully,

For SS you can use any head that's on the accepted list. After all the welding and epoxy they all come out the same. Just stay away from any casting that has a history of cracking.

Thanks, Guy's I already have my dogs looking for castings.
