I currently have a low compression 350 short block in my 68 impala. It has the 291 camel hump heads (1.94/1.5), stock (929) cam, rpm intake and Q-Jet. I just converted to a saginaw 4 speed and the car has 3.36 posi out back. The 4 gear is fun, but runs out of steam around 4,000 rpm. I eventually plan on building the original 327 to L79 specs, but in the meantime I'm debating about either putting the GMPP 350 HO cam in this engine or... now you'll know I'm crazy.. I also have a 69 307 short block in good condition. I have thought about "something different" and putting the 291 heads on it, and then going with either the 350 HO cam or the old 097 Duntov solid cam. I also plan on adding headers (car already has 2.5"duals), and would use the rpm intake. I know it's a heavy car and it has A/C, so don't want to get too crazy with the cam.
Also looking for advice on cylinder heads. I have a pair of Aerohead 434 castings with 1.94's, screw-in studs, etc., but feel the 291's are probably a better head. Also have a pair of 487's, but that would drop the cr too low. Just curious of the flow characteristics between the heads.
Looking for any and all opinions.
Thanks,
