Ram Air IV vs: SD455

[caj]

Ok Pontiac gurus and enthusiasts. Here's one for you. What is the rarer, more desirable, fastest engine between the 70 RAM AIR IV and the 73 SD455? I know they are both underrated and rare but given a choice between the two....what would be your choice and why? Thanks, Craig

SD ....... Because I have one [img]<<GRAEMLIN_URL>>/smile.gif[/img]

I've driven multiples of both versions and the RAM IV is hands down the more exciting car to drive from listening to the thumper cam all the way to winding them to 6500 with no valve float. I know that the SD is the more rounded engine but it does not have the same effect of driving a RAM IV. AND YES I HAVE 1 that I would put up against a SD

RAIV is MUCH rarer in a Firebird.

And its price exceeds the SD.

I can remember a time when their price position was reversed.

Ive driving both 70 RAIV and 73 SDs since 70s and its a very close call but I go with SD because it had all the right parts and stayed together .

Lotta neat history behind the SD, but something about a IV just does it for me....

There's nothing like having a low 13-second car in 100% factory trim, that can run on 87 octane! (For us old cheap bastards). [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

First of all I've never seen a SD Car run a low 13 in 100% stock form.
If your talking about the 1st test car,I think that car was a ringer put up by pontiac and note it's not a air car which most were. The 2 I drove and beat the snot out of were both air cars with a 308 gear I think and I personally was unimpressed. That's not saying a 4 spd non air car with a 342 might be the one your talking about but those are far and few between. Lastly I really doubt you or anybody you know runs that car on 87 octane. If you do you really are a CHEAP BASTARD!
