Carb style intake manifold ? 's Is it worth it? How much power did you guys pick up? I am thinkin of putting 1 on with a 90 mm TB and sheet metal elbow. What did you spend after all said and done?
Thanks

well alotta guys say its worht it it you need the intake for your power output. im going single plane, but keeping a carb, not EFI. it really depends on what your goals are i suppose,... oh and i have a dual plane LT1 intake for sale if ur interested

I will keep that in mind. I have the LT4 Edelbrock intake. The car is honestly a big ole turd below 4k but it pulls like a freight train around 5 to 7 k. I have been told my intake is whats killing me. I have ok gears 3.90's.
Right now my motor is around 540 at the crank I have been told goin carb style will pick it up around 50 if thats the case I dont mind spending over a grande on intake manifold.

Are you spraying? With your cam (high 240s IIRC?) you will want more aggressive gears then 3.90s in a NA 6speed. Some 4.11s minimum!

I will be spraying in the very near future. If I was goin NA I would definately put 4.56's in it but I was just trying to squeeze what I could from the motor to run a lil smaller shot. If swapping to a carb style manifold would pick up a lot with out changing my cam or doing more head work then I would do it but after talking to all of you and others I dont think with a HR camshaft and a motor that will not spin more than 7k I dont think it would benefit me too much and the money would be better spent somewhere else.

I really want to stay EFI with this motor man or I would. It just frickin sucks that nobody will come up with an intake manifold that we could just bolt on better than this piece o **** LT4 Edelbrock. Maybe if I threw the stocker back on there and ported it I could pick up more low end

Well if it was a solid roller it would pull hard all through the power band and not only above 5k which is the problem or not a problem but my preference . I want this thing to boil the tires at 4k not wait til 6k to decide well , its time to wake up.

Badmoon, I have a REAL nice fully ported LT4 on my motor that I'll probably be selling when i get my tax return, I ended up making 480 rwhp on my setup with it on 100 octane, probably would have made more on c12. I would look into a cam from Bret Bauer, the cam he spec'd me was for a single plane and I still made rediculous power EVERYWHERE with the LT4 manifold. Peaked at 459 rwtq, and made 405 rwtq at 2800 rpm, 450 rwtq at 4000. low 240s/low 250s duration. Hydraulic roller lifter on mild SR lobes, and low, easy on parts spring pressure. Fastfatboy is running a SR cam from him, and his times speak for that combo.
