Car: '88 IROC-Z / '91 Z28 / '91 GTA
Engine: LT4 Hot Cam 305 / L98 355 / MR 383

Axle/Gears: 3:45 / 3:23 / 3:23
*NEW* LT4 Hotcam and GMPP Springs
New LT4 hotcam, never installed. $140+ shipping
This hydraulic roller cam is for service only for all V8 engines with roller camshafts. The duration at lash point in degrees (intake/exhaust) is 279/287; duration at .050" tappet lift (intake/exhaust) is 218/228; and maximum lift with 1.6 rocker ratio (intake/exhaust) is 525/525. Valve lash is zero/zero and lobe centerline is 112 degrees. Technical Notes: The LT4 camshaft P/N 24502586 was designed to be used in a number of different engines. Therefore, the following change may need to be made to allow for correct assembly of the engine: For LT1 and L98 engines 1995 and before, the dowel pin in the end of the camshaft must be pushed in so extension from end of cam is .30+/-.01", the same as the production part. For 1996 LT1 and LT4 engines, the dowel pin is in the correct position, extending .620" from the end of the camshaft. This camshaft has a fuel pump lobe.
USED 16 Valve Springs GM PART # 12551483 Previously used, they look new to me. $60 + shipping.
This single valve spring is use on 1996 LT4 Production Corvettes and ZZ4 crate engines. Technical Notes: Single spring with 1.32" O.D. and 1.22" solid height. The pressure at installed height IS 101# @ 1.78" with 332# the average rate of pounds per inch. Use with retainer P/N 10168424.
Prices OBO. I accept paypal (plus 3.9% fee), money orders.

bneuberthz - the cheapest I could find the springs are $6.15 each from gmpartsdirect. I am open to offers, but at this time, I'll pass on $20.
chevy_toolman - I'll figure out the shipping for you, and yes I accept paypal as stated in my first post.
