Can I keep my factory A/C in my 67 if I drop in a '67 BBC?

I know factory A/C and a Big Block were not available in '67
however if I decide to drop a 1967 Big Block 396 into my '67 RS Convertible
could I still run my factory A/C unit?
could I still go with a TH350 Transmission? or would a TH400 be better?

Re: Can I keep my factory A/C in my 67 if I drop in a '67 BBC?

Wow - My 68 is a factory A/C car and my small block just barely cleared. The headers had to be modified to fit. I would guess you'll have real problems getting enough clearance for a big block even with factory manifolds. I ended up taking my factory out (can't get the old Freon anyways) and installing a vintage air system. That moves everything behind the firewall and gives you plenty of room in the engine compartment for a big block.

It fits, I think maybe a different evaporator unit might be needed.

Re: Can I keep my factory A/C in my 67 if I drop in a '67 BBC?

It will fit and was offered as an option on 325 and 350 horse 396 engines in the Nova which shares the same sub frame and inner fenders as the Camaro (I have seen them installed on 454 BBC Camaro Z/28's at car shows).

A/C was not available on any engine equipped with a flat tappet cam because you will blow the front seal out if you over rev the motor with the A/C on (works fine if you remember to turn the A/C off before any demonstrations of speed). Modern cars that rev to 6,800 RPM have the car's computer turn off the A/C compressor as the RPM gets above 4,600 RPM.

A TH350 is torque limited. It was relabled as a 3L60 tranny to let people know that it was not as strong as the TH400 (aka 3L80). The numbers after the L tell you the torque rating of the transmission. I wouldn't use any 60 or 65 rated tranny behind a BBC.

Nova inner fenders are not the same as Camaro. Flat tappet applies to both hydraulic and solid lifters. Subframes are similar but not identical. Being a "Z/28" has no impact on the configuration of which you speak, neither would a base model, SS, etc. SB and BB A/C suitcases are different like Don stated.

Sorry I meant to say solid tappet rather than flat tappet.

I included the reference to the Z/28 because there were so few of them built in 1969 with the 454 engine option.

I have gotten Nova and Camaro front ends to interchange (of course I couldn't open the doors but it bolted up). I did this just to see what it looked like back in 1972. Just can't find the photograph I took of the '70 Nova with a '68 Camaro dog house on it (I bought a one piece fiberglass front end for my '68 Camaro and had it lying around). Ran a full fiberglass front end on the Nova (including bumpers and mounting bumper brackets front and rear and fiberglass doors and trunk lid) using individual pieces that I bolted together using aluminum bolt and nuts. Painted it to look like a rusty front end I found (different color than the body) and applied fake rust colored patina as paint and talc powder). Because I built a lot of 427/454 BBC powered sleepers back then, as I got tired of class competition (mostly gas class or M/P).

The Big Block evaporator box has a different suit case. Its angled towards the fender to give more room for the exhaust manifolds if I remember correctly. I have a stock 69 camaro with big block factory A/C. The suit case is different from a small block case. Hope this helps! Scott

Yeah. None. Dave, I'm assuming you were being glib?
