When I get ready to do it, think I'll call Comp Cam's hot line.. and get a recommendation..

Just do it right: begin with checking the cam card for your cam and see what spring pressures and heights are recommended for the cam with 1.6RRs. Should be at least a dual spring. Suggest going with non-self adjusting RRs with the guide plates and hardened pushrods----check your geometry to ensure the correct PR length. SB std length, but better to make sure.

If you bring each cyl to TDC you should be able to change out your springs without dropping the valve into the cylinder. Be sure to get the proper spring compresser for the job. For that matter, be sure to check out all recommendations on this board regarding the RRs, Springs, PRs, Guide Plates, etc.

With the additional lift and a bit more duration, along with the proper combination of parts you should get the maximum power out of your cam along with a solid, well-controlled valve train. JMHO

?????????? That a blank statement?????? I have no issues running LT4 springs with a Crane 227 cam w/ CC 1.52 rockers..... It all depends on the setup that is being used and all the components work together for the engine to achieve maximum potential......

..........and yours is probably not achieving its maximum potential with those springs.

It's really not that big of a deal to change springs while it's still on the car.....I had nightmares about doing it, bring each piston to top dead center and it works out great....dont sweat it and good luck either way
