are the PRC dual springs overkill for a TSP220 cam? Will anything negative occur running them?

Thanks

 

actually there a good spring for that size cam!

 

Good! For some reason i thought i went overboard. Agould i get new lifters while im at it for cheap insurance?

 

Ive got the same springs in mine with the same cam. Have 35k on them and still going strong!

 

im running them for about 20k on my 224 so far without any issues. i plan on swapping heads soon and am going to run another set of them. lifters are a good idea if you have high mileage and if you plan on pulling heads, otherwise its not necessary

 

i've ran PAC 1218's on bigger cams and never had problems..

 

so your point is? whats your opinion on the prc's?

 

90k on rhe engine. New lifters?

 

i did not change lifters when i did my cam swap .529 lift (123k miles) yours is at .581? its really up to you.. if the heads are stock i would wait on the lifters until you upgrade the heads.

-how hard are you going to run the engine?

 

not too hard on a day to day basis. It will get beat on from time to time though I'm just wondering if the extra spring pressure is going to hurt the old lifters.
