I have wondered how my 65 Valiant 2 dr sedan would do with the 273 in it. I want to get back on the track, but I want to be able to go rounds.

I am considering building my '64 Valiant sedan with a 273 two barrel, it seems to fit in P/SA and some of the guys have had success with this engine in B body's inj lower classes.

Just my opinion Jim......... but the four barrel 273 looks a lot better to me. I believe the engine is at 220 and can run Edelbrock Alum. Intake. The Wongs and Bushmakers both run the combo and are FAST. The old Mopar Race Manuels aways suggest not running a 2 Bl. in a class that can run 4 BL. My boys 318 Wagon in P/SA can run Small or Large Thermoquads (up to 800 CFM) and a very efficient intake allowing it to Spin 7000 RPM comfortable. Every time we have tried a 2 Bl. it just doesn't want to run much over 5,500. There is a racer in Vegas building a GT car with 273 2 Bl. and I am watching to see how he does.
Also be aware that the Casting # on 915 only needs to be correct.....No matter when it was cast on Julian date IE: head can be cast a different year than car it is on if casting # is right!

Just my .02 for what is is worth .. .......John Irving

Yea, I know that I have several sets of each (ya know "borninamopar) but I don't think the 915 with the 1.72 exhaust would be legal to run on a 64 dodge with the 383. I think john was talking about the 66 915's with the 1.60 valves as that is what came stock in 64 in the 383. I may just build the R/T it looks like it may be more competitive anyway. I might build them both and see which does better.
