Edelbrock Heads for 318

Back in the early 70's some racers were limted to 305 cubic inch's and all of them put a 3" crankshaft in the 340 blocks to get 305" out of it. Sure they could have sleved it for smaller pistons or put a longer stroke crank in a 273 block but no, RPM's were what matter cause the rules did not say how fast you could spin the motors. So they were running 13-14-1 compression and 8000+Rpms. If they would have went with the smaller pistons and longer stroke crank they would have not been able to spin the motor so fast. Now of days with this crapy gas we can not run 13-1 compression but if you could a short stoke motor would come out on top every time if it had the right heads and cam. RPM's wins over stroke. The faster you spin the motor the more air you can pump in and out. Sure long stroke motors are great for low compession RPM motors but thats only cause the short stroke motors can not spin 8000+ with 9-1 compession. The cam and heads are too big for 9-1 for any low rpm's but if 2 same cubic inch motors had 13-1 compression and unlimted choice for heads and cam-and good gas-the short stroke motor would make more power cause it can spin much faster.
