Hello I am trying to put together alittle mild street car..
The shortblck is rebuilt 355,
I will either be using some double hump heads, or some mild ported votects, I am not sure what cam and intake to use.. It is a non roller block..... I am using auto trans and a 3800 stall... if it matters i will be using 100 shot of nitrous on top of this and its a carbed setup...

 

Stock crank, stock rods, ARP rod bolts; Speed Pro forged pistons; whichever heads; the Edelbrock RPM intake for whichever port location; Comp NX274 cam; Manley Street-Flow valves; Comp 1.5 1300 series rockers; 800-850 CFM Holley DP carb; 1¾" headers

 

what kinda power could i see outa this

 

Probably near 400 HP plus the nitrous

 

If they make an NX282 grind, go with that over the 274...you have a 3800 stall.

What rear gears and tranny are you planning on running?

 

Double hump heads may not have the accessory holes so you may want to think about using them.

The biggest mistake I made (other than retaining the 882's, and using a 1974 350) was not paying attention to "quench". Optimal I was told (after engine build) is around .040. I used a Felpro Blue head gasket that has a compressed height of .039. If I had "zero decked" the block the quench would have been in the optimal range. But I didn't deck the block or shave the heads. They were in very good shape and I knew the history of the engine for most of its life span so I left it alone so the quench is around .064. I may now take the heads off and go back to a steel shim.

 

Some double hump heads do have the holes; some do not. There is NO WAY to fake the holes if the heads don't have them, that will produce satisfactory results. Which is why you can pick up the old ones without holes so cheap.... they can't be used in cars built in the last 30 years or so.

These are 186 castings.
