Will these manifolds fit my 2003 Lq4. I'm putting it in a 1937 Chevy and I need some block huggers, but the stock ls7 manifolds are much cheaper to buy.

Any other reasons not to use the ls7 exhaust manifolds. I've tried searching everything I could find about them to get info. Does anyone have a measurement to how far they stick out from the block?

If not that, how far do the GTO exhaust manifolds stick out from the block?



Thanks,
Brandon

They will bolt on the engine not sure or the measurements I usually use f body manifold myself when I do swaps

Not sure if the ls7 manifolds will work, but ls2 and ls3 manifolds from a vette are the same design roughly and will for sure fit.

Ok, thanks for the replies, guys.

If you have some ls7 manifolds available I would try them, they flow amazingly. You would need the beginning of the rest of the exhaust though to mount to their oval exit.

I don't actually have any yet and I don't have any manifolds to test before I buy so I'm trying to make sure I buy the right ones the first time. (i have the old truck manifolds that I know won't fit).

There's a guy on a Vette forum that says he has some exhaust manifolds for a 99 C5. I've been measuring and it's just really hard to tell without holding them up to the car.

Thanks,
