What about these cam specs....
Intake duration at 0.050" Exhaust duration at 0.050" Intake lift, cam/valve, inches Exhaust lift, cam/valve, inches Lobe separation angle
235 235 0.320/.480 0.320/.480 114
I know its pretty mild but considering the stock 90 L-98 specs it should be a mild improvement shouldnt it? Those specs are with 1.5
I might be able to pick up a cam like this for little or nothing from a local engine builder. I'd plan on using it with stock heads, stock runners, ported plenum and ported accell base. (possibly a superam later on)

....you'll need to upgrade the heads, intake in order to maximize on that cam. ...and exhaust too.

Hyd. Roller Cam; Lift: .474" I, .510" E; Duration @ .050: 208° I, 221° E
These are the specs for the ZZ4 camshaft with 1.6 RR
Would this be a better choice I wonder.

Since your not bound by emmissions it would be feasable. Most smog legal cars top out with 219 dur. cams. The whole problem with a hot cam is it's peak power might be produced at a higher rpm point than the intake air flow will allow.
Also big duration H-Roller cams are an Oxy-Moron. Your limited to @6500 rpm because of the valve train weight.

Re: What about these cam specs.... (gkull)
Thanks for the info. I was a bit worried about the duration being so big and with any tpi system valve timing is allways a huge player. I may go with a zz4 cam since I can get one locally for $100.
