hi i have an aluminum headed l98 from a corvette i want to put a cam in it but idk which one...i plan on doing heads in the future but not now

so i guess i would need a fairly mild cam i want the best one that can be used for a stock head l98

if you have a write up or link on how to install that would be great too cause idk how

 

IIRC, all '88 and up 305 and 350 TPI motors used the same roller cam.

 

idk about that, im almost sure the 305 auto's had the small cam. The 305 Manuals had the 350 cam, which allowed them to red line at 5500

 

dont want stock tho.....im talking aftermarket what would be the best for what i want

 

My bad, '88-'89 305's and 350's used the same cam (part # 10066049) whether is was auto or manual
'90-'92 305's and 350's used a little smaller cam(part #10111773) whether it was auto or manual

 

For a computer controlled engine, try one with duration at .050 lift of 202-205 intake and 206-214 exhaust. Most cams with these figures will have between .415"-.460" lift with stock rockers. Most of these cams will be emissions legal. You didn't say if your engine was efi or carb or whether it is computer controlled. Doesn't matter it will run smooth regardless. Hope this helps some.

 

where are you getting this info?

 

Pages 75 and 76 of CAMARO PERFORMANCE HANDBOOK by David Shelby. The book with the blue Z28 on the front cover.

 

that does help thankss...and im sorry didnt mention but its the same engine in my avatar just a tuned port aluminum head l98

 

why does the 305 manual and l98 rev higher than the lb9 auto?

All 305 TPI (LB9) engines (1985-1992) came with one of two basic cam grind profiles. An easy way to identify the type of cam on an LB9 car is to look at the tach: the lesser cams have a yellow line at 4500 and red line at 5000; the hotter cams have a yellow line at 5000 and red line at 5500. All camshafts 1987 and later use hydraulic roller lifters
