How much more hp would you expect to make from a 327 vs 283 (using same cam, carb & cylinder head)?

Should be almost the same assuming the valvetrain can handle the extra RPMs.

Using 500 for a good 283 SS engine, math comes out to 1.76 per cube times 44 more rounds out to about 77 more hp. Have never ran one maybe someone could tell use what a good 250 hp 327 makes. Tom

A 327 will have a lot more torque than the 283. Also, using the same heads( I assume a set of #520's), the 327 has a drastic compression edge.There is a Div. 7 racer, a Mr. Solano, that has a blue 64 Malibu hardtop with a 327/250 horse combo running in J/SA that has gotten into the 11's pretty handily, that with the 4 jet and all. The 68 low compression 250 horse engine isn't anywhere near as good in bad air. It falls on its face pretty markedly. The 283, however, will make RPM like nothing else.That's where the horsepower comes in.

In my SS car with the car weight real close to the same the 327 250/258 is about 2.5 tenths faster than the 283 220/230 which uses the same heads, intake and carb. I don't know the actual HP numbers but that is what they are on the track for our car and motors.
The 283 makes the power about 1000 rpm higher than the 327.

Am curious as to wether the 590 heads have a distinct advantage over 896-460-or 523 heads?

Besides 8 HP, anyone know what the difference is between the following 327's ?
This is for SUPER STOCK 63-64 327 250/262 and 65 327 250/270

62/64 327 ran 283 Power Pack heads with 1.72/1.42 valves 65 - 327 used larger 1.94/1.5 valves which are perfect valve size for that size engine. D |
