single/dual plane intake

The engine is a 347 stroker. Cam specs are adv dur of 286, dur @.050 of 230, lobe sep of 110.0 and lift of .598. A comp cam. I really do not want to change cams right now, maybe this summer. My goals have changed so a milder setup is probably best. Currently dynoed or 2 yrs ago at just under 480 at flywheel. Seems high but is a nasty rumble. Also, no choke on carb.

That cam shouldn't be that wild. I think an RPM Air Gap would suit the engine well. If you're having hesitation issues, it's most likely a carb tuning issue.

The lift is very high for that mild duration. I have not seen that cam listed. Is it custom from Comp Cams?

(high lift) ? It looks like that's "advertised" duration.

A 35-450-8 or a 286H-R10 by comp cams

That must be one of the two versions that Comp Cams makes specifically for the stroker 302 (331/347). I have seen them in Jegs.

With 286 total duration and .598 lift. I still believe that is a lot of lift the that small amount of duration.

However, if it works, it works. Just hope it lasts. With that lift to duration ratio, it can put a big strain on the valves.
