My guess is that you can use the 318 stuff as long as you change to a new hydraulic cam and lifters. That would probably be cheaper than to try to find the stock adjustable stuff for a fair price.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Also, the Isky E4 is a good grind for the 273.

Ran a Performer intake on my 65 273 with no problems. You can run a later intake on the early 273, just not the other way around. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

The performer or any other later style intake will not bolt directly onto a 65 273 head. Your heads were swapped for later heads or the bolt holes on the intake were wallowed out.

Run a CR of 9.1 to 9.5 E4 Isky solid Cam Find a set of 920 casting heads (66-67). They flow the best. They flow better running a stainless 1.88 intake valve cut down to 1.82. That way there's no shrouding. If you can't find that casting 302's are a good alternative. Run a Edelbrock LD4B and a Carter 625. Of course a good ignition and exhaust. 273's make power as long as the RPMs are up. 273's like a lot of gear. For a street A body with a 273 3.91's are a good start.
