the whiplash works very good in the low comp engines

SB or BB or B or RB they all work great.

member Lew has the black car on there web site to advertise the SB one in a stock 340

member Junky just went with one in his 383,he seems to like it and said it gave a good improvment over his other set up IIRC

maybe he will chime in on the specs of his 383

I dig the SB one and will be getting the roller cam whiplash next and will be getting one for my stock lopo 440

It does what they say it will do..idles like a funny car and smooths out about 1800 rpms for street cruzing and stop light to stop light action

I give it
