Hey guys i just wanted to know if some of you guys could post some et times.I am building 350 tbi w\edelbrock heads and crane cam,670tbi etc. and i wanted to see if anyone was running a set up close to this.to be honest most of the times i see in here are no to great with tbi so i was thinking of a change to tpi? the best my cars has been is a 14.52@95. mph w\stock 350 from pace performance' edelbrock tbi intake'headers'3 inch ex.a eaton posi 373.gears and slicks and a tci 700r4 trans w\2800 stall and custom chip. thanks

 

I'm really surprised your not running better than that. Those are times that I expect out of my 305 when I get the tuning dialed in a bit better. You say you have a custom chip. Did you tune it yourself?

 

My best time was 13.65, 2.1 sec 60' with a best 102.1mph. Xfire Corvette running 3.07 gears and stock tires.

 

no the chip is by fast chips,this a stock 350 truck motor w\the swirl port heads the cam is only193 dur 385 lift@.50 so the cam 'heads' and stock t\body are killing me. i am looking for easy 13s high 12s on motor after the change.

 

the 670cfm tbi prolly isnt killing you as much as you might think. Like you said before, heads and cam. Definitly ditch the heads and cam before you spend the $ on a tpi system. swirl port heads are horrible, unless all you want is low end torque.

 

Sounds like you need some of the 083 heads. They are the 350 TPI's. Should be alot better than the 350 swirlports.

 

My 383 TBI (Crossfire) ran a best of 12.81 @ 107mph last year. 60' was 1.76sec on normal street tires.
Usig AFR195s and a mild hyd roller 216/220, ~500lift.
Will be racing tomorrow night if the weather is good, fingers crossed for a new best!
Ben.

 

Swap h/c, but do the ultimate mods with your stock throttle body.
