lt4 cam spring i found a great deal on a set of lt4 cam springs. but im putting a cc 503 or 305 cam in my car and im wondering if these springs will work or do i need to get diffrent ones. thanks
the LT4 hotcam set has 1.6 RR's, and the 503 is compareable size to it.

The 503 lift with 1.6 would be 0.536"/0.544", 305 is 0.544"/0.544". The LT4 springs were made for the stock LT4 cam which had a lift of 0.498" and they were just suitable for the 0.525" lift of the hotcam.
Hey similar question guys, I have a mostly stock 97 lt1 formula, and i am looking to purchase a lt4 hot cam and the corresponding lt4 valve springs. My question is can the car run well with the stock 1.5 rr's or is it a requirement to move on to the 1.6's?
also are their other necessary mods needed for my lt1 to move well with the new cam and springs, thanks for the help. -D

The LT4 springs are marginal for a HOT cam with 1.6s in LT1 heads due to the heavier LT1 valves. Do yourselves a favor and consider them ONLY for stock cam/1.6 applications and not for any cammed applications.
