Can I squeeze 300hp out of my TBI 305 with just a cam, bolt-ons, and tuning? I have been thinking of replacing the motor with more displacement or a TPI intake, but I could live with it at this level of power.

------------------
'91 Camaro RS - dark red metallic - '91-'92 Z28 wheels - leather - all power options (except power seat) - t-tops - Clarion head unit - Pioneer 4way 200watt 6x9s - Rockford Fosgate Punch amp and 2 Fosgate 12" subs - Edelbrock open element w/ K&N filter - Random Technology highflow cat - some free mods, more coming soon...

 

IF you had a good cam, good heads and bigger TBI you might could probably hit that nomber, or you can just use 125 hp shot of NOS and have the HP at your disposal.

 

I want to reach that number without power adders. I know that 1hp per cubic inch is very possible these days, I just don't know if I would need to change my intake.

 

I highly doubt you can make 300hp N/A with the stock LO3 heads. In fact I will say its not possible.

 

If the does the above mod's AND sprays he'll hit the number at the wheels assuming the fuel system can supply the gas.

 

get some larger heads, cam and an intake. buy some chip burning software, and be prepared to take a few months to get all tuned. and you could get that much out of the 305. but never much more than that without internal work like crank, and new high compression pistons etc.. that is the case where you might as well be working on a 350 block.
