What do you pull the 40ft trailer with now?

Curious as to why you recommend no less than a 1.55" spring, PAC makes some springs that could get him the rates he desires

3-4 month hiatus Started mocking up the engine cylinder heads over hang the bore a little, I think I'll notch the stop a little on the intake side I'm degreeing the cam in now, the proform kit for LS engine sucks so I'm going to improvise a little and then return it. After that I'm going to mill the...
