Original 383 from 67 Charger that has been 30 over previously. Only option is to go 60 over. First question is the block sufficient (non HP)?
For heads, I’d like to see if the TF 240 would work but the bore is slightly off as block end up at 4.31and TF recommends 4.32. Concern here? With the .60 bore, and these heads, looks like compression is 10.4 with the pistons flush.
Car is 4 spd w 3.23 sure grip. Most likely will stick w Factory manifolds to keep sleeper look.
Street only, lower end torque is goal. Idle quality important. Power Brakes.
With the rambling above, what are thoughts on intake( I know I’m limited) and cam?
If anyone has traveled this road, I’d love to hear from you.
TIA

I did mine 383/496, .030 over. I used 440 Source heads, roller rockers, stroker kit. Used RPM Performer intake. I "Know" for sure I'm never going to be chasing hp or racing it. So the CNC ported 440 Source heads are more than enough. I used a Comp hydraulic roller cam for longevity w today's oils. I based my build around this build but 496 and hydraulic roller. At the crank I got 610/670 hp/tq. I used the below cam. Idles at 850 in drive w 13" vacuum.

I agree with @diesel_ lv as far as what he used for a cam and heads. His #'s are plenty for a street car! With that said, I used 400 block and built a 512 and used the TF240 heads and the recommended hyd roller cam w/ .600 lift. Also used the edelbrock performer RPM intake w/edelbrock 800 CFm AVS2 carb. It spec'd out a 10 to 1 and is very snappy! I have no dyno #'s. hope this helps. ruffcut

The 440 source heads are my first choice but they have no ETA for availability. Could be months, even more. The TF has an estimated date; which is really the driving factor for its selection- finding something in stock! ( or hopefully by Spring).
Appreciate the details on the cam- I’ll compare to the recommended TF cam and see where power is. Finding something that starts low to 5k would be ideal. Appreciate the article- very good read.
I’m guessing with the TF 240 I might be somewhere between the articles power rating and what your actual dyno rates? Upper 500 range? That would be plenty for this sled- although some weight savings planned for front end as well.
 
Building a 496 now Eddy rpm heads and Rpm intake Hughes cam.Roller rockers 850 carb. 10.4 To 1 Factory HP manifolds Will dyno it this spring I have the same motor in my other car. Didn’t Dyno it. Very street able with lots of power
 
If I were to build a stroker and run manifolds (I wouldn't) , I would have a cam ground for the application. I believe the older mopar .528 solid cam fared well with manifolds.
