The oval ports I had on there were only good for 322hp and a 12.80@106 with 4.11 gears and couldn't even pull the 3.25 gears I switched to. On the 2-3 shift the engine bogged down.

What heads do you suggest I get to run with like 80cc chambers? I couldn't find any with chambers smaller than 99cc.

I wish BBC's were as easy as SBC's My last 350 was all cast with machine shop flat tops and aluminum Pro Action 180's with a XE274 cam and Prof Prod intake and it made 276 RWHP. It was good for 13.24@105
