If someone is running a stock 302 block, they aren't very serious about horsepower, lol. They will split in a hurry. The mod blocks will hold the power but the internals are crap.

 

And when people talk about "crazy," they aren't generally talking about something that somebody can do (full weight, at least) with stock LS1 internals, either. I'd love to drive a properly-setup 400rwhp GT to see what it's like.

 

Dog ****, thats what its like.

 

Lol wut?

 

I've always heard the stock 2v block is good for 400rw in most cases...?
Few push 450ish with some luck but 400-420 is as much as most feel comfortable with.

 

It's the stock rods that are only good for 440-450 rwhp, the mod blocks have taken up to 2300 HP according to the Mod Father.

I've been to a stock 302 block race and I can promise you they are making more than 400 rwhp with stock blocks. Far as I've seen, stock 302 blocks can take around 475-550 with stock internals...with the rotating balance zero balanced and and a good tune, I've seen them last with over 600 rwhp. I'm not saying they will last a long time at over 600rwhp, but they will last a little while.

 

I've seen them break at h/c levels too. The problem is we don't know what people are doing to keep any of this **** alive. Could be half filled blocks or more, girdled up **** or many hours spent in stress relief.

 

Stopppyyyyyyyy..... Only 3 more days, that is all. Lol. I ordered a set of caltracs but they won't be here in time :/

 

I cracked mine at 530RWHP(16psi S trim). Totally my fault. Temps dropped and I added a lil timing on top of a Larocca tune with race gas added. BOOM.

You break one with heads cam you are a moron....

 

Yet more stupid **** out of your mouth. What is it Hiho...do you just think of something real quick and throw it out there?

"girdled up **** or many hours spent in stree relief" wtf does that even mean?

"How did your block stay together behind that turbo!!!???"

"Dawg....I massaged that bitch with my hands for 2 weeks!"

 

3 more days til what? Sechs change tiem?

 

All a girdle does is hold the two halves together when it splits. Pouring concrete in them would probably help if they had weak cylinder bores like a 400. Breaking all the edges of the mains wouldn't be a bad idea, since it's the thin main webbing that starts the block splitting in two.

 

Well having to put a hole in the block for the cam I'm sure doesn't help either. All the 302 blocks that I have seen split, the crack goes right through the cam hole.

I've never seen a block split while N/A unless there was catostrophic failure due to a rod or something like that.

 

This x 947217234

However I do like main girdles because they do help with cap walk.

 

To the track!

 

Make sure to take a helmet just incase you get out of the mid 13's!!!

 

Oh no you didn't! I plan to get alot of videos lol. I'm expecting mid 12's first time out, but no idea @ what mph. Any idea? 110 maybe?

 

Man I couldn't even tell ya. PM me all the details, I'd like to give it my best bench racing math.

 

Stress relief block

 

Hell, I just rub my own sack for stress relief..
