69 L-78 Cam Specs?

[Chevy454]

being a roller you don't have as much wiggle room, but you can gain some vacuum from adding some lash...it basically makes the cam looker smaller to the engine. i've seen some of the l88 & zl1 guys run lash up over .035" so they could pick up some vacuum. i run the crane blueprint (actually it's a cnc copy now), and have like 16" around 1000-1200 rpms.

btw: if you'd like a stock 143 blueprint cam, i can probably get one for ya... [img]<<GRAEMLIN_URL>>/wink.gif[/img]
