LS7 427 or ZL1 427??

I love old school but If I was to do it again It would be LS all the way.

I agree with Frank, save a boat load of cash and do a simple Ls3 setup and spend the money elsewhere.

My ZL-1 doesn't leak or overheat. I'd like to inject mine someday. Not sure that will happen as I'm tired of spending money on my car. I'd rather spend money using it.

The real question comes down to what you intend to do with the car and what suits your budget and taste.

If you want to go al bbc, why not get the Brodix block?

It appears it will more easily support extra cubic inches . At least go 540 if you're going to buy a rotating assembly anyways.

Weight, the brodix block is 60-70lbs heavier.

I don't even know why you asked this question. LOL!! LS all the way baby!!

Need one more vote for LS? Okay; LSX all the way!!!!!

I'd vote LS, but I am an LS guy not a BBC guy.

Power levels may be similar but you will be happier in the LS when you are driving past the BBC guys at the gas pumps.

Old, but just wanted to ad.

Summit list the Brodix block as 142 lbs.

ZL1 shows 110 lbs.
