No sense in beating around the bush

It is a new build sitting on the stand but never fired.
The converter is an untested piece as well. Its supposed to be 4800-5200. Actual car weight should be closer to 3200lbs with my fat ass on board.

Thanks!

307/313 @.020"
278/284 @.050"
199/204 @.200"
.723"/.678"
106 lobe center
.020"/.022" lash

With correct clearances, keep the valve train stable with a stud girdle or shaft mounts and your close to the 10.0 mark in that combo. That combo as cast will run 10's and should sixty foot high 1.3's to low 1.4's

Th400 with steel valves. This is a street more strip orientated setup. 7500 rpm would be theoretical max rpm give or take a few 100.

Thanks!

Oooof............the cam posted above is WAY too long for your combo!!! Do not put a 278 @ .050 lobe in a 357 and expect it to move a 3400lb beast to 330'. It isn't going to happen!!!

I agree. It was disregarded.

The cam that's currently installed in the motor is 266/274 @.050 -.640/.640-108.

Its what I had sitting collecting dust so I stabbed it in. I am now questioning it before the motor gets installed.

Thanks!

Are you looking for a off of the shelf grind cam or a custom? Also what do you have for valve springs on these heads?

If an off the shelf grind fits that works for me but a custom deal is fine too.
Springs are Comp 954, they lists them as 210 @ 1.90/ 524 @ 1.25 coil bind 1.17. They are setup @ 1.90 with a Ti retainer.

Thanks!
