A mid sump should work for you. Its what was used in my 86 and a friends 94 Chevy trucks.

what major mods have to be done besides flipping the sbc mounts and the driver side firewall cutting

I don't recall having to cut the firewall, but than again the previous owner of my truck had a caddy motor in the truck before I bought it from him. I bought the truck with a sbc that blew a head gasket so we decided to go the caddy route again since he had all the swap parts. He didn't flip the motor mounts as he had made some steel adapter plates to bolt the stock caddy mounts to. We also ran a set of Sanderson headers that were suppose to be a direct fit. We ended up having to trim the frame some and hammer in a few of the header tubes to fit properly. The only pics I have since I had no digital camera than are in this link...

A Caddy 500 weighs less than a 454! You can find performance parts and info at http://www.500cid.com/Home.htm

ive already talked to marty on what cam i should use for towing from there

I think there may be some clearancing needed around the oil filter (RH front).

I think that depends on which filter housing he uses. I beleive a 425 housing will allow more clearance. I can't recall what we had used but will try and find out for you.

if you use a manual tranny you'll have to machine the rear of the crank to accept a pilot bearing since they all came with auto trannys.

The SM465 is very strong. The gear set is pretty heavy, which lends itself to strength but it also stop you from doing any power shifting, which again will make the trans live longer.

You could probably use a BOP bell housing, but I believe the opening for the input bearing retainer with have to be machined larger, as the input bearing retainer on a SM465 is larger than that of a car transmission

[Slofarmtruck]

I am usure how well that trans will hold up. I know that there are very few manual transmission that can handle the torque of the caddy motor. I was researching running a Muncie 4 speed in my new project car behind a caddy motor and ended up choosing a TH400 for now, since my results yielded transmissions that were way out of my current price range. For sure a Tremec TKO600 will hold the power but they cost $$$. Might want to contact the guys at Cad Company with your trans question. http://www.cad500parts.com/

[Slofarmtruck]

Talk to the Cad Company as they have alot of manual trans swap parts. Their Billet Steel Flywheel is a thing of beauty!

[BukuBandits]

i called cad company last week on the trans adapter and flywheel total cost is about 500 but he said it is a direct bolt up and do not have to machine the crank for a pilot bearing i know they have everything needed for the swap. and obviously this truck isn't going to be taken to the track or anything but i would like to get on it here and there and not worry about the tranny blowing apart

just got off the phone with cad company trans will definitely hold up to the abuse

That is great news!! Please post pics of your progress!

[BukuBandits]

can anyone post some pics of motor mounts or trans adapter hooked up

[spinem]

i remember seeing a 67-72 build years ago.... never this year.. PICS!

[Slofarmtruck]

Mine was in an 84 C10 with a TH400 trans behind it. These are the only pics I have. Hope they provide some help.
You can see the breather on the drivers side under the vacuum booster is crushed in so that it would fit.

[BukuBandits]

thanks for the pics and how much diff are the mounts for the 67-72
