LT! Engine info?

[SSDan]

I just bought a 1946 Chevy Truck with a 1995 or 96 LT1 engine with aluminum heads. I know there are limited things you can do to improve it's performance.

While looking at the Summit catalog I notice they have 52MM and 58MM throttle bodies available. Will they help and why would you want the smaller throttle body?

They also have a Grantatteli Air Flow Sensor, will it make a difference in the engines performance?

I know he engine has a reverse flow water pump running off of the cam. Meizere has an electric replacement pump for the LT1. Would it be a wise investment or do you forsee problems?

Any other ideas would be appreciated!

58mm is the normal size to step up to when modding, but would make very little difference on a stock or mild combo. With a cam swap, ported heads, and headers then yes, otherwise spend your money in another direction.

That engine uses an electric fan. Meziere has an electric WATER PUMP, which would not add much power again for the money.

The wideband a/f kits are useful for tuning, the narrow band type are not accurate enough for wot tuning. Best bang for the buck to wake the engine up would be headers and exhaust, tuning, cam, and then ported heads. Start with the exhaust and tuning , then cam, then head and cam if the budget fits.

I'm tight with the purchase of the truck and finding out my Chevelle 468 engine was about to blow, so I'm building a new engine and there are other problems I have, more than you want to hear! I appreciate the offer and advice!

I will change the exhaust and cam, but for now, it must wait till next year. I have too many irons in the fire!(GRIN)
