very mild cam,what other equipment are you using with it? that cam should have nice manners in a big engine

i told the builder i wanted a lumpy idle but enough vacuum to run my brakes..with what your saying it sounds like its not enough lope..dang! The vehicle is a med weight 1931 5 window coupe. ( about 24-2500 lbs guesstimate)adj roller rockers w/ guide plates, bored .030 over, rear axle ratio is stock 70 LIncoln at 2.73's. It has a top loader 4spd, 2" headers, 3' lake pipes with auger style baffles installed. N-50 tires for the rear and F78 14's in the front. A Weiand Stealth Manifold with no carb picked yet.

hydraulic cams sound lumpier than solid counter parts.I prefer the extra power to the lumpy sound. closer lobe displacement angle makes a choppier idle.

The LSA is 110. What is the cam duration at .050"?
From the cam card.
What cam is this?

Never mind I found it.
This Erson "TQ40H" cam is fairly mild.
220 -228 @.050"

It will not have a rough racey idle if that is what you want.

If you want a rough idle you would want
a different cam
Try Erson cam #E260526 "HI-Flow III H"

316-316 .545 .545 108LSA

This cam has 240° @.050" intake and exhaust duration
108LSA and the same .545" valve lift.
For best results the cam should be degree'ed in and
installed on a 104 intake C/L Thats 4° advanced.
Do not guess, degree it in.

It will have the rough idle and will need the distributor recurved.
24°-26°@idle 34 to 36° @ max advance. (short,limited 10-12deg advance curve)

The idle will be plenty choppy.
use a 750 holley or 750 Edelbrock carb

rough idle, good power from 3200 rpm up may want to increase the rear gear ratio.

Another good similar cam choice with a rough idle
would be a Comp Cams "Thumpr Cam"
comp cams #34-601-5 287TH-7 Mutha Thumpr"
Degreeing it in is recomended. This cam already has the 4deg advance built in,
when properly installed.

Some of the Ford engine timing gear sets are retarded.
Degreeing in the cam is always recomended with these motors.

This mutha thumpr cam will need the same distributor curve modification.
