What was the tpi on a 92 Camaro?
My brother owns a ’92 Camaro that was equipped from the factory with a 305 TPI and a 5 speed. It ran high 14’s and low 15’s with a homemade “cat back” and Flowmaster muffer. Nothing to write home about. With a set of L98 heads and lower intake that I ported and an adjustable FPR.
Is the 305 TPI good for a Camaro?
The 305 is definitely not the first choice if you are starting from scratch. But if you have one and are on a tight budget you can make them go fairly well. Besides the same top end parts can carry over to a 350 later on anyway. Which is what he ended up doing eventually. Some 50,000 miles later. Stock 1.94/1.50 valves. No problem.
What kind of head does a Camaro 305 use?
Replaced World Products 305 S/R Torquer heads with ’96 – ’97 Chevy truck L31 Vortec cast iron heads, GM P/N 12558060. These are available from GM dealers in the USA for US $408 a pair, fully assembled. The Vortec heads require a different intake manifold, and Car Craft chose an Edelbrock Super Victor. They kept the same Holley 750 DP.
Why does my IROC Z 305 Ping so much?
You will get some pinging due to no EGR flow, but if the idle or just off idle improves, the EGR is opening too fast due to carbon buildup inside the valve and must be replaced.

What kind of Cam do I need for a 305 TBI?
You can snag a used vortec L31 cam (same thing as 350 B Body LT1 cam) or even better is a used 1994-1997 LT1 Z28 cam. All can be bought used for under $100 and with a nice stage 2 chip can get you to 200hp or a bit better.
How big of a bore does a 305 TBI have?
The stock 305 and 350 TBI unit has 2 (1 11/16″) bores which flow 450 cfm of air. Up to 230hp engines that air flow is fine. you can do the ultimate TBI mods to the stock 42mm TBI unit and get that air flow up to 500cfm without increasing that bore diameter which is plenty for any 305 engine that you can run with TBI.
