Going Roller on my 340!! Solid or Hydraulic??? Pro's and Con's
SSG what are your thoughts?? Same build?
My build looks like this so far:
1970 340 block, .060 over
4" arm from BPE
Callies compstar h-beams
Race-tech forged pistons
W2 race heads fully ported
1.6 HS rollers
Mopar dual plane intake
850 demon
Going into 72 Duster, 4spd, 3.91SG, 28" tire
I've been seriously leaning towards the solid roller (with mrl lifters) in order to utilize the full potential of the W2s. BUT, this is going to be primarily a street car with only the occasional drag strip run, so the hydro roller may be a better choice to minimize maintenance, noise, and wear caused by higher spring pressures with the solid stick. As of now I'm going solid.
I will be tubing the block and installing a crossover line in the valley but will not bush the lifter bores.
As far as OP' s setup, I'd recommend the solid roller to maximize the potential of the heads in order to get into the 10's. Guessing that he will do more serious racing if he's trying to hit those kinds of numbers.
