You have to realize the intake port arrangement is more like a BBC than a SBC,meaning no paired ports.To balance the flo they must have had  proof that it was better to have the carbs positioned where they are.I like a tunnel ram myself over a X ram.Pontiac had a factory tunnel ram avail over the counter for their 421 SD program way back in 1962.Tom

Pontiac just went cheap with the 366,they used a std 455 piston and just ordered a rod that would connect the piston to the crank!My short deck engines used a 6in BME alu rod.Tom

Both engines I built were 100 percent pump gas street engines.I built them to be able to turn 9K.I have found from years of testing all kinds of CI RA V engines from 366 CI to 455 CI in street trim and with a factory dual plane intake they give up around 6200 to 6500.The 366 engine made 448 HP at 5800.I ran it for years in my 69 Firebird.I ran the X ram on the dyno but with 660 center squirters and it did not like it.Never ran it again.The guy that owns it now has run the X ram engine in his 69 TA with a set of 450 holleys and has not reported how it drives.The 366 NASCAR RA Vengine im building now will have a single plane intake and when we run it on the dyno we will see it it likes it better.Only rub is I dont think it will like the 7in rod in the std deck block.Tom

I will dig them out.Just shipped my last complete RA V tunnel port engine out today to TX.It was a std deck engineering 455 engine.Tom

Great reading.I have owned 2 of the 25 built SCCA short deck engines.I have built them as stroker RA V tunnel port engines and have ran them in both a real 69 T/A and a 69 T/A clone.I owned the X ram2-4 RA V intake and correct tall tach drive dist for them also.I am now building a std deck true NASCAR 366 engine also with the RA V tunnel port heads.Because pontiac only made 25 of the short deck engines they were not allowed to run the series.They then had to go to the std deck 303 and ended up running RAIV heads.I also at one time owned a RA IV short deck 2-4 X ram intake.
