If you found one of these race cars today how would your restore it?

The down side is nothing makes that kind of sound unless you have some ungodly compression which a detuned engine will not have (correct me if I am wrong here). I just love that sound.

----That's what everyone always said about Red Alert once my second rebuild went back in the car, Rick. 14 to 1 compression just makes a great sound!.....Bill S

I don’t agree with that at all. I have a RAV pro stock engine 13.6 to 1 compression and a D port low compression 9.0 to 1 turbo engine in my other car. They sound exactly the same. You’d never be able to tell me which was which. My turbo engine even when not I. Boost sounds angry and nasty! Just like my RAV engine .

Kind of hard to hear it the sound quality sucks in this old video

Same cam same CR same CI I dont think any diff in sound on a RA III engine and a RA V engine.Been there done that.JMHO,Tom

Tom we were talking about the difference in compression ratio in the sound not necessarily the d port Vs V port . I only used the V and D port because that’s what I had for comparison in my garage in different compressions, and wanted to explain the difference . That the RAV was a higher performance version and higher compression. Yet the D port lower performance engine w low compression sounded the same . In fact most people who hear both side by side idling feel the Turbo car sounds nastier and snottier even though it’s far lower compression , smaller cam , and blows through the turbo which knocks down some decibels. . RAV is a roller cam 650 lift range about a 112 LSA and the d port turbo car is a solid flat tappet in the 550 range 114 LSA.

I’ve built RAIV both ways stroker w low compression and original w high compression and I dint feel there was any dicernable difference in the way they sounded. We are really only taking about 1 point to 1.5 points of compression between the two on those engines if the original is built to 1969 NHRA specs even For a stock eliminator to a drivable on pump gas stroker RAIV.

Compression DOES make a diff,sometime BIG.Tom
