So here is what I plan on doing with the '73 that currently drives real nice with a built 350P, 670 heads, 1968 Iron 4 barrel intake, 800cfm Qjet and Hooker 1 5/8 headers. Th350 little stall converter and a 1968 4 pinion HD 3.36 diff fitted to the second gen.

The new heart for the car is:
A 1970 400 2 Bolt studded mains zero deck
6.8" Forged rods
Ross forged flat tops ( 8cc valve relief)
Forged crank 4.25 stroke
CR is at 9.5 using thin cometic (.028)
Holley street dominator Intake ( SD Dave still has my '71 HO intake)
800 CFM Qjet
Mallory Unilite with Vacuum adv.
Dougs 1 3/4" 3" coated Headers
Heads are SD CNC ported #46 irons with flow chart attached ( Springs and installed height with be changed for the cam)

Now for cam I really wanted to use the original Old faithful from Dave ( which I have in stock) but I am second guessing myself ( maybe not enough CR, rear gears, headflow CFM)...
So I found here a baby HR from KRE ( 232-238) that may work with my Solid lifters I planned on running on the OF ( Cam cards attached )

The car is a 1973 Esprit, along with the 461 engine swap, its also getting a new drivetrain and fuel system to feed the engine and Nitrous system (200 shot)

Jakes Performance Transmission TH400
Continental P1D PS Balloon plated "3200" stalled 10" converter
3.08 Posi 8.5" 10 bolt. diff
245 60 15 tires all around
Bilstein suspension and subframe connectors
2.5" transverse H piped exhaust system but I have a Pypes Full 3" with X pipe with Borla XS and 3" tailpipes I could use for this car if needed for max potential.

Engine ( rings and gap), fuel system (stand alone) and transmission are built to deal with a regular 175-200 nitrous shot in mind (plate).

The car is not a race car but will see quite a bit of local semi serious street racing duty while my LS7 BBC Camaro is getting its refresh next summer.

What you guys think?

What Cam would you run ?
( the smaller 232-238 KRE HR would most likely get 1.65 HS Rockers, but will use 1.5s if I end up using the Old faithful.

How would you optimize this set up?

the 51-000-11 cam will make more compression because of less overlap.
My 7:8:1 motor sounded a lot more healthy with a cam like yours.

The smaller cam will obviously create more DCR and cranking pressure, while its not always a good thing with pump gas..

It would be a no brainer if like you, I was at 7.8 SCR but im currently at 9.5 CR and still can shave the heads and go to a more traditional .039 for the Head gasket and still get closer to 10 CR if needed and clean up the idle or create more idle vacuum ( which neither are really needed with the OF and this car has manual brakes
