    I have a very nice survivor 1941 chevy. I dont want to cut the firewall. I am looking for any advice on what to look in to or is there a nice reasonable bolt or weld in kit out there? Thanks.
    It will be backed by a turbo 350 and nova rear.

    Shouldn't be a problem as hundreds if not thousands of SBCs have found a home under 41-48 Chevrolet passenger car hoods.

    Chassis Engineering in Aimes, Iowa has what you want. With their kits you can add a M II suspension, small block Chevy, TH 350 trans, and upgrade the brakes. All bolt in. Good stuff too. However I like the Posie's rear spring kit a bit better for the rear end install.
    These are MY opinions, your milage may vary. Read the fine print.

    The only beef I have with chevs of the 40's is you cant ask a technical question. No tech dept.........

    How do your rear springs ride? I was told the Chassis Engineering springs were a rough ride.

    Rode in a friend's car years back with the CE rear kit and it was a mite rough. I've done two now with the Posie's spring kit, and I've been happy enough with the results. Got a 48 Fleetline Aerosedan thats waiting it's turn and it will either get the Posie's springs or air ride, ain't decided yet. But I do like the CE parts except for the rear end install kit.

    I have a set of SBC bolt on engine mounts from C.E. that came with the car. Issue is the car came with a Mustang II suspension and those mounts are for original suspension only. Waiting for correct set to arrive. Don't believe the firewall should be an issue yet the body is off the frame at the moment.

    I put a 327 in my '41 in the '70's saws all out the trans mount mock up the engine and trans and weld up the mounts and build a trans mount from angle iron. week end project! the trans cover won't fit:mad: speed way has a good brake/master set up. I used '57 chevy rear springs(and '57 rear end) I followed a magazine how to article. i was just a kid and it walked me thru the whole swap! I think it was a Rod and Custom

    the distributor will fit in the firewall like it was made for a V8. exaust will be to tight on the steering column. but it works

    Probably, but with that heavy car you probably won't be happy. I have a 40 with a homebrew Pinto frontend. You should really consider the Must. 2 conversion.

    I stand by my statement. He won't be happy. My 40 is around 31-3200 also. Full a/c, p/s, p/b, 700r4, etc. IFS is the way to fly.

    I put the CE front cross member in my 48 chevy and the CE rear spring kit. My rear rides like a pickup so as per CE advice I removed the 2nd leaf from the bottom and it helped a lot except for big bumps. The only thing that I still don't like, is the extra long a arms of JW Garage are still not long enough so the front wheels have to be spaced out futher with very little back spacing or spacers. I love the bolt in front adjustable cross member as most of the weld in cross members make the car to low for me. The front sway bar is not a shoe in so I found the rear is good enough. I did get the front installed but it took some work and a lot of sending parts back and forth as there are two different lengths of sway bars. I would go with the guys who say Posie's have a good rear setup. My two cents, I hope it helps and good luck
