I would like to use a short CH piston to get it real lite. I really want to science this build out as it will be my last go fast build and chance to break into the 9's. the next one after that will be a bb stroker just for cruising and to show. gonna get away from chasing numbers and sell my trailer as well. anyway I really want to get this sb right this time around.
My  , I would sell what you have, build a BB pump gas stroker that will be able to cruise around and run 9's  ...I don't see the point in spending all the money twice on the SB when you are going to go BB in the end and be able to reach your goals

I'm sorry but I have no pictures at this time. I always did mine by hand with a carbide burr but that's just me. I would try it first on a piece of scrap metal to get some practice. Remember its not a big crazy chamfer. For example on a small block head ( 1/2 inch bolt ) its only gonna be like 3/16 - 1/4 inch max 45 degree chamfer. Just enough to spread the pressure from directly under the bolt head.
1970 Duster
Edelbrock headed 408
5.984@112.52
422 Indy headed small block
5.982@112.56 mph
9.42@138.27
Livin and lovin life one day at a time

Disagree about a long rod killing off power, that isn't true at all.
In fact the guy who owns my old car has been 9.62 at 140 with it at 3200 pounds on super stock springs and 28by 10 DOT tires. That is with off the shelf headers and a 727 trans.
Don't know of many, if any, similar W5/ Indy combo's that run any better.
To the OP, we're it me I would mill the heads if you have flat tops to raise compression, run a cam to match the compression, and swap the 727 you have already for a 904 .
The tranny swap should be good for 1.5 tenths, and a little more cam and compression will knock another 2 or 3 tenths out of it easily.
I would be willing to bet another another point in compression( to 12.5 compression) the correct cam, and the 904 would get the car into the 9's.
This all assumes the heads are good.
If anything those heads have a bit more potential than W5 head, which has smaller valves and less cross section.
Doesn't take anything special to get an A body in the 9's with a roller and Indy heads

When I originally joined in on this thread, I thought the OP was building a stock stroke 360......... The long rod would be brutal in that...
