Hey Guys i'm swapping a gen1 400 sbc into my 95 camaro and need to know if the stock radiator will be sufficient.

The motor will be 427ci with 235cc heads
296/300 duration cam
should make about 650hp at the crank

And this will be in a street car so keeping it cool in the nevada heat is a BIG concern.

Mine has never gotten above 200° during summer with the ac on in lake havasu az. I think it was about 115° that week.

Hmmmmm. Thats a lot of engine. If it were me I would try the LT1 radiator but plan on a custom aluminum with Electric fans. Is it a track car or a street car? A/C ???

Street car with AC. I plan to drive it everyday

The LT1 radiator should be sufficient. But always prepare for the worst so go ahead and budget for a custom radiator.

LT1 rad will be plenty fine for that engine, just make sure you use a good pump.

There are half filled boosted LT1s making more then that to the tires on the stock radiator.

I know its kind of off subject and doesn't help much but from my understanding the lt1 radiator is an upgrade if installed in a ls1 car. I may be mistaken though.

Mine cracked from age last year and I asked the same question and got the same answers. The stock is plenty. I went with another stock one.

Thanks for the help guys.

i will be using a professional products super hurricane single plane intake. and a nitrous outlet intake elbow. I'm going to try my *** off to keep everything under the stock hood. But might end up with a cowl hood

I am not sure how good the radiator is, but I do know that gen 1 400 sbc run hot due to the siamesed cylinders with no water jacket between them. Just keep an eye on it

I run the LT1 Radiator with my 408 in my 84 MCSS, and I crammed one in my 1991 LS1 S10..IMO its a damn good Radiator.

LT1 is 1" thick, LS1 is 7/8" thick.

And you were a GM Tech?

Sounds like you're just mad that it's not yours....

OP even with a siamese bore the LT1 radiator should be plenty. X2 on wanting to see this done. Good luck with the project.

The 97 radiator is 1" thick, the 93-96 is thicker.

Alright now that is enough!!!! NO ONE cares who has the thickest one.... comparing them is just immature.
