Can't Decide 76 Toro with a 455

The manifolds above are reproductions of the 442 manifolds. The cast iron 307 manifolds will work but will pull your exhaust pipes up and out with the 455. A good aluminum replacement rad should do, how many cores? I would only get a 2004R only if it has a billet foward drum, deep pan, good clutches etc. CK Performance is a good shop to contact.
It's a Cheap Spectra Premiumm CU162. 1 row Aluminum with Plastic Sides. It doesn't say that it will work with a Big block so I'm assuming it won't. I was thinking 2004R Because 4 speed, I've heard good things About the Art Carr ones. It's annoying to decide but I might just get a High Torque TH350 and save some Money for the inevitable unexpected expensive things.
Just throwing in the motor stockish the rad should be enough to cool it as long as you don't go crazy on ignition timing
A 200-4R and 3.42 wI'll be epic with a stone stock 455. It will run on pump gas.
Those 442 reproduction manifolds would be the way to go. Probably get a new or reman starter, as the Toro part will not fit.
I think that aluminum single core will keep up, it has 1 inch wide cores.
After it's done you will ask yourself why didn't GM make em that way.

I used that rad with my 350 and never had overheating problems. No shroud either.
With the shitty 307 rad in my 88 Cutlass with an Olds 403, under drive pulleys and 5 blade 307 clutch floored the temp gauge quick. That rad should be adequate. I would use the fan off the 455 with the stock shroud. Actually you want a lot of timing with that 455, it will run better. Also if the 307 has it's stock small starter it will not crank the 455 when hot. I forgot about the Toro starter being different. A mini starter is a good option and pretty much necessary for headers down the road. You can use straight pattern sbc starters on the Olds V8.

I think the biggest problem you'll have is to find a new name, 307 Gutless just aint going to cut it...😀
