Tapping / Ticking Noise? OK let me first start off with this ?
Does anyone know what a base circle on a ms4 measure at compared to stock?
My heads are the prc stg 2.5 heads with prc 660 dual valve springs ! I was running a pushrod lenght of 7.4 (tsp recommended ) !
We'll I broke a valve spring outter one and just decide to replace them all along with new pushrods 7.425 iin hopes that this would quite the ticking down !
It did at first but now i seem to have a very weird ticking sound at idle and it doesnt seem to always be constant !
This is a new motor with 2700 on it ls2 402 ms4 camshaft prc stg 2.5 heads the are 66cc flattop pistons with 2cc vavle relief!
Should I try a bigger pushrod ?????
The car still pulls very hard ! The best i could get at the strip is a 7.66 at 98 mph with a 2.34 short time ! 1/8th mile
Anyway I am at a loss here as what to do! all advice and opinions are welcomed!
Many post i have read guys are saying some of this is common as these motors are noise and this cam is noisy aswell and long tubes just make it louder!

i dont think that the base circle is any larger on the ms4 compared to stock. its your lift that the tick would come from, no?
ls1 valvetrain = noisy
ls1 valvetrain + bigger cam + headers = super noisy
if that helps any :/
