about 275+ HP with some good bottom end torque. I have the opportunity to get a 99 chevy vortec block and heads. do you know if an Edelbrock #3704 TBI manifold will fit on this long block and if it will bolt up to my tranny.
I know I'm probally a little late, but here is my 2 cents.

Trash your stock swirl port heads. They are not worth the time or money to trick them out.

Get those 99 Vortec heads. casting number should be 10239906. They will bolt up to your exiting block.

Then buy yourself the GM Vortec TBI intake P/N 12496821.

That intake will bolt up the Vortecs, your stock intake will not.

You can then bolt your TBI unit up to it & do your chip tuning.
