340 Street Build

The parts you have so far look good to me.
Very similar to my 340 that runs on 91
Since you have adjustable rockers I would go with a Solid Flat tappet Cam.
Just too many issues with Hydraulic lifters these days.
Solids will almost always make more power and rarely need adjustment.
Really no down side IMO
keep in mind when comparing Solid to Hydraulic cams, a Solid will have about 8-10 degrees more duration @.050
(To account for lash)
So around 238-240 to be close to that Comp. 230 your looking at.
Talk with a Cam company like Bullet or Howard's for their recommendation.
Have Fun with your project!!
Thanks. I was planning on calling Howards and Hughes Engines when I get more information after tear down. Also considering Jones Cams. Hughes claims to have a better lobe/ramp speed setup for the Chrysler engines designed around the 904 lifter. Hughes also mentioned having some "Stiffer" than stock lifters in the 904. Any experience with Hughes in this aspect? I may also consider the solid flat tappet. I wasn't sure about using a solid for street application and I don't have much experience with the solid lifters (Except for setting lash on an old VW bug) my wife had 30 years ago.

I ran Sealed Power hydraulics lifters in that SBC. Put a lot of hard miles 100k ++ on that old 73 Nova. It was my daily driver as well. Hard, I mean drag racing folks with several 1/4mi runs every other weekend but I was only about 18 or 19. I'm sure it was nothing like folks on here do but to a kid it was a big deal. Oh what memories!
