Late 90's dak has no prob supporting true dual exhausts,the cat was turned sideways...I was just offering suggestions within the budget he proposed,and without getting internal,is his sons trk so how far he goes has both of those things to contend with...

1st thing I would do is put a true duel exhaust on it,not a cat system,you can get a obd2 catalatic dual in dual out,think mine came 2 1/4'' but had muffler shop open it to 2 1/2'',,run 2 1/2'' pipes and retain your sensors,I ran headers also,think we ran some type of glasspak mufflers,also had...

Sorry..Wasnt meaning to compare to the cheaper ones was trying to promote away from them to something better such as the prw's or better quality stuff,aint nothing worse than a cheap set of rockers with breakage and ruining a good engine and wasting a bunch of coin and frustrations...

Exactly my point,this is what I have and have seen work great....Kmj perf has pretty good reviews and strive to be customer orientated and research out their suppliers and screen out junksters,they actually test this stuff before they promote it or sell it to the public...I have many positive...

I and a friend of mine have a set each of PRWstainless steel roller rockers from KMJ Performance,his being 1.5's and mine being 1.6's,ball and ball style pushrod application..no fulcrum bearings but bronze bushed,seem to be a pretty decent set-up I'd say comparable to comps pro comp stainless...

Yes the CH4B-440 equivalent to LD340 in popularity in the past,were the intakes to have,they worked in the good ole days and for street cars today they can still hold their own,always gonna be something better or flow more etc...but these do respond well also with a little work,nostalgia at its...

Thanks for the reply...anyone else got input?

Anybody used them,know much about them?the pros and cons versus reworked factory castings,915-906-452-346-516's...I know they were 86cc had raised port design,what kind of flow #'s,chamber design etc...

:happy1::coffee2::happy1::coffee2::toimonst::coffee2::happy1:............anyone gonna comment on the vacuum ???...........and no comments on MA MOPARS low comp tests?? How about the stage lV heads in comparison to factory castings ported etc.?

Sorry, direct lube solid lifters,with hole in face like Howards,Lunati etc..

Just picking brains here about the pro's and cons of solid lifter edms,what are the advantages or disadvantages to using them,are they worth the effort? To me in my mind seemed like a good idea and better oiling on the cam but I dont know much about them,so who has used them and opinions from...
