Edelbrock 3713

[91s104x4]

I may have a chance to purchase a 3713 TBI intake manifold cheap. My question is, how much power would a piece like this make on a stock engine with a few cheap bolt ons and TBI mods? If it's nothing special like another bolt on then it's not worth it to me. If I run this manifold I will also run my fuel pressure around 14psi. What do you all think?

I'd say 15-20 hp with free-flowing exhaust. 5-15 with stock exhaust.

Well worth doing, but it helps greatly to have the exhaust to compliment it.

my exhaust is stock 2 1/4 factory piping with cat and a freeflowing glasspack in place of the muffler? Glasspacks shoud definitly be free flowing.
