Have I made the right choices?

Xstream_1 said
I have just finished putting together the 318 for my 68 fastback ( my very first engine build ). I have 30 over flat top pistons, Edelbrock RPM Performer heads w/ 2.02/1.60 valves,stock crank and rods, Comp Cams 270H, 270 dur. 470 lift, 1.6 roller rockers, aluminum dual plane intake, TTI headers, 600 cfm Holley, I have a 8.75 rear geared 3.55, and 904 trans with a 2800 stall. I am curious as to whether I have made the right choices for a street machine that will see limited track use. Thanks in advance.

Here's some food for thought? I/We have a 318 std bore and parts, 9973 heads which are 318's from 75-76 engine we use a .509 comp cams cam and adjustable rockers, to get the most out of the cam. Then the heads are gasket matched and bowl blended, we also used a M-1 intake and 1 5/8 hedders with a 750 vacume secondary carb with mods to the fuel metering. We have the total timing set at 30*, with a modified stock distributor. The engine runs on 87 octane gas with out any problems the actual compression ratio is 8.9:1 the little engine makes 440HP peak @6000 and 357 HP to the ground, the torque is 427 @ 4500 peak and 327 to the ground the 1970 duster ran 12.20s spinning through low gear only due to the stock suspension, with M/T ET streets, the car hits the scales at 3100 and change with the driver. We are looking for mid 11s when we get traction and tuning corrected.
We have tried the bigger heads/valves route only to be dissapointed, so we backed it up and the little engine responded instantly. We used the 1.78 318 intake valve and used a 1.60 exhaust valve from a 360 head. The head cced @ 132 on the intake and the exh. @ 52ccs, the chambers are 64 ccs. The int. flowed 213 cfms and the exh. flowed 190 cfms. The hedders are 38" street type dyno-max.
I hope this gives you some more insight.
