89 L98 engine project

[Utah]

Finally took my vet out of storage this weekend, was able to finish dying the blue carpet to black which i started last year, and the blue door panels had what looked like greese stains from when i bought it so i painted them black too... changed the whole look of the interior for the better!

Next i took it to a performance shop as after replacing the heads last year, i needed to redo the bottom end. the plan is to tear it apart in the next week, and then decide from there what can be put in it for more HP!!

im not too big on engiens, but mechanic was talking about cams.. any suggestions

ZZ9, ZZ409, Lingenfelter 219. these cams seem to work real good with TPI L98 cars.

You can't pick your cam until you finalize a lot of other things. Decide what you're going to do for heads and intake as well as what your plans for the bottom end are. Once you know all of this, then you'll be in a better position to pick the correct cam for your application.

Good luck,

Ron

That TPI unit isn't going to do you much good on high end HP. At the very least, you should get it ported.

Our TPI intakes were originally designed with the 305 in mind.:eyerole

As Ron eluded to, the most important thing is that everything works together. You don't want too much cam without enough intake system or visa versa. There are many other variables to consider as well.

If you are only rebuilding without grandiose modification plans, you do need to go to a cam that will take advantage of the rollers. The factory used basically a flat tappet grind that didn't take advantage of the roller followers as it could have. Their only goal was to reduce friction, which they did accomplish.

If everything else is staying stock, then go to a very mild aftermarket cam that is designed as a roller grind. You will realize a gain from that approach.

The 74219 Lingenfelter cam suggested in an earlier post is intended for a 383 and would NOT be a good choice if you are simply rebuilding to basically stock. For the stock rebuild the Lingenfelter 74216 would be a much better choice and would not require valve train or head modifications. It would just bolt in and work quite well with your stock heads and valve train.

Good luck,

You need to pick a final HP goal and try to stick to it. That will determine the best course of action.

However, I think a ZZ9 would work just fine for any of the 3 intakes (SR, MR, modded TPI), if youre on a time deadline on getting it together. It just may not work 'best' with SR or MR.

How hard was it to dye the carpet and does it hold up? I want to change my blue carpet to black and was considering replacing everything with new.

Thanks,
Dino

LPE claims the 219 is for a 350 on up, and works best with their SuperRam. It'll work just fine on a stock-sized engine. I'm in the process of proving their claim... stay tuned .

Dino - I started dying it last fall and I was using actual carpet dye from a body shop. It cost about 20 bucks for a spray can. It worked good but then started to fade within weeks.

This time I used straight spray paint, figuring if it didn't work, I planned on replacing it all any way. So far so good, however I have not been using the car since its in the shop so I cannot tell how much use its going to stand up to. I will keep you informed.

The 219 will WORK in a stock size engine if you don't mind the rougher idle and slightly decreased low end torque. The most IMPORTANT reason for not using it for a simple rebuild is the fact that it has pretty high lift. MAKE SURE YOU CHECK VALVE TO PISTON CLEARANCE if you use this cam in a stock engine.

Best of luck,

Is .560 really that high a lift? It's right on the edge of needing double-wound springs. LPE said nothing about having to worry about piston/valve clearance issues, even when installing it in a stock roller block.

even TPiS said piston to valve clearance with the ZZ409 cam which is .555" lift on 1.6 rr's is ok.
