I will be swapping out the 305 for a 350, getting a short block from a 97 truck. I'll be putting on a pair of World S/R Torquer heads, ZZ4 Cam & an Edelbrock Performer TBI Maniflod. My question is will my stock TBI be good enough or will I need a new TBI unit like the Holley 670. Or can I just change the stock injectors for bigger ones. Also, will my stock fuel pump be good enough?

 

A 670 would probably be a big improvement for your setup, especially with a 350.
Buy some prom tuning equipment, you will need it.

 

I'm using the Turbo City throttle body,afpr and the 454 injectors on my 350.

yea id definitly go with the 670 cffm throttle body, on a side note hows the perfromance diff on ure car now with all ure mods done- gears, headers, catback,shift kit, open element, fan switch

Thanks

 

with all the mods that I've done so far compared to stock, the difference in performance is like night & day. I dont have a before & after comparison cause I have never been to the track but I can definitely feel a huge boost in performance. I cant wait to drop the 350 in & upgrade the rear suspension.
