TBI 5.7L to EFI Multi-Port Edlebrock Conversion

[gtj]

Dear Group,

 

Anyone have any experience with the TBI to EFI multi-port offered by Edlebrock.

 

http://www.edelbrock.com/automotive/index.html

 

With recommended heads, cam and headers they report adding 81 ft/lbs. torque and 80 HP. The dyno graph shows a nice torque curve improvement in the typical driving range, IMHO anyway.

 

Any input appreciated.

Seems lot a lot of bother and expense. You could just use the upgraded intake that Eldebrock offers for TBI systems that support stock TBI unit and a oversized one as well and put in a warmer cam if you want while the intake is off (you are halfway there anyway with intake removed). Stock cam and intake restrict the TBI engines output more than anything else. Upgrdae those items and you will see a noticable improvement.

I installed the package you are talking about in my last truck 95 gmc 1500 4x4.I definately picked up some ponies how much I don't know.Personally I would not get the mpfi and get the upgrade intake like snoman suggested and see what upgrades there are for you tbi.Get the aluminum heads,cam,intake,and a custom tune and you probably get more ponies than edelbrocks mpfi with there chip or piggyback adapter as they call it i think its on the conservative side for smog reasons.I believe theres a company in arizona that modifies the edelbrock setup and was putting out around 4oo hp with there own injectors different tune and what not.if i can find the name ill post it.Knez

That Eldebrock TBI manifold look like it flows well and should help a lot especailly with a oversizes TBI unit on it.
