Does any one have any idea how to get more power out a TBI 5.0L chevy motor? I got headers, 3 inch full exhaust into a flowmaster, 14" air cleaner, MSD Blaster coil, MSD 6AL ignition, and NGK V-power spark plugs. If any one has any ideas please let me know. Thanks.

 

carb it 100 shot nitrous 2200 stall shift kit 410 gear=flyin

 

350/carb swap

 

i'm going with some of the basics here heads and cam..lol

 

HOT ROD's 400hp 305

343hp 305

 

computer computer computer you will find what you need there I will bet

 

nope...





nope again..


the prob with the tbi cars were the heads. half the intake ports are blocked off to cause swirle. they get good mpg and ok tq at 2500 for daily driving. but thats it. nothing but better heads will make power on these things.


after that, you can treat it like a carb setup. just have to add fuel and timing with the computer instead of a screwdriver.



the cars are rated at 170hp at the crank stock, so i'd say you may be up around there to the wheels now, with your mods. just watch out what heads you pick, if your going to put them on the 305 now and then plan to build something bigger later. the 305 should be a 58cc head, anything bigger will kill comp and not flow to great anyways because of the some bores.



edit* you prob could port the heads like in the link above, but i still think aftermarket heads are money well spent. i've read that the stock ones are thin wall casting to save weight so porting worrys me.

 

Honestly I wouldnt spend anymore money on that roach than you already have. You are pretty much at teh limit.

Edelbrock makes an intake manifold for it, but im not sure how much gain you will net....


I had the same car.

 

350 ftw. 305 = teh suck

 

I Dont Care What U Say I Say Yesssss
