What would be the cam i need for my stock l98. I just want mild performance because its a daily driver. Not that rough of an idle, but enough to hear. I know its not gonna make that big of a difference in my car without some other things to go with it.

And quick questions:
Bigger cam equals more or less mpg?
How hard is it to install urself?
Possible to do it with engine still in car?

 

Call or email Your favorite Camshaft compay for a recomendation. thats what their tech line is for.

Something around 212in/224ex @.050" on 112-114LSA is a nice upgrade without getting carried away on a stock or near stock L-98.

Quick answers

1. Usually.......the most common mistake in going to a new cam grind is over camming the motor. Pick the cam that fits your rpm range and real world driving habits. If you have a near stock motor, stock torque converter and 2.73 rear gearing, don't get a big cam.

2. It's a bit of a job. Will take you all day at least.

3. Yes you can replace the cam with the engine in the car.
You have to remove all the engine acessories from the front of the motor , remove the rad and ac condenser.
remove the rad support brace infront of the rad. remove the intake and distributor. and timing cover.

You'll need a harmonic balancer puller and a installer tool.
(K-D Tools) Moroso , Proform tools.

A good time to replace the timing chain and gear set too.
(Crank gear puller)

Get the right valve springs for the new cam. Most "Extreme" grinds need new valvesprings. Some of which need cylinder head machining. Some use drop in replacement springs. Consult your cam grinder.

This is probably a stupid question, but cams for a chevy small block will fit in my t/a because it has a GM motor wont they?

 

Yes. It's a Chevy Gen I small block engine. You will need a roller lifter type cam - more expensive than the typical performance upgrade flat-tappet cam, but you can reuse your stock lifters.
