I havent been finding any help in my searches and pm's to various members, so can someone help me on this please.. I hear Manley Nextek springs are a long lasting and very good spring for a solid roller motor, can someone tell me the part number for these and the hardware needed? Also what lifters are you guys running that have long life and work great, part numbers there too.. For a Lt based motor if it matters..

 

Isky Toolroom springs are what I use for endurance solid roller.

 

Crower Cutaway Severe-Duty lifters and PSI springs. Don't have part #"s.... the engine was built 8 years ago.

 

got any numbers for the isky springs? Is there anything special about the lifters when buying them, like how tall they are?

 

We would need much more information on your heads before pointing you towards a specific spring(Installed height, retainer part #, guide diameter & height, cam lift and durations, valve head dia. & length), it takes a lot of time to set them up correctly when they're sitting on the bench in front of me - you should take them to a machinist who can take all the proper measurements and supply you with a set of parts that will all match and work together.

 

Le3 Lt4 heads, 2.08/1.60 valves, cam would be a custom le cam (.660-.680) lift, 24x/25x duration..
