Projected build help
Alright, here's the story. I've currently got this build going on, and I'm wanting some opinions on my judgment to see if I'm going on the right path here (I'm curious about trying a solid cam is basically what it comes down to).
Current build:
- 355, 10.5:1 compression ratio running forged flat tops
- fresh reworked 882 heads
- XE274H 230/236@50; 490/490 lift and 110 LSA
- Quickfuel 750 Annular
- Edelbrock Airgap RPM
- Hedman Longtubes
- TH350 with manual valve body, 2500 stall
- 3.42 gears
Projected build:
- 355, 10.5:1 compression ratio running forged flat tops
- Dart Iron Eagles 200CC's 66cc chambers lightly ported and polished and decked (currently have these sitting upstairs as we speak); Harland Sharp 1.6's with Dart stud girdle
- Lunati 401A6LUN Solid Flat Tappet 243/251@50; 518/530 lift and 110 LSA
- Quickfuel 750 Annular
- Edelbrock Airgap RPM
- Hedman Longtubes
- TH350 with manual valve body, 2500 stall
- 3.73's or 4.10's
*553/565 lift with the 1.6's in place
Also, after looking at another solid cam (401A3LUN), I found one a step down if this sounds any better..
238/248; 485/503 lift and 112 LSA .. Essentially the smallest of their solid cams; not sure how much a performance gain I'll see from it.
Do these sound balanced? I also plan on possibly stroking it later with these parts in place, but we'll see. I don't have any idea on what kind of power I'll be making with this projected build (or my current one which I'm putting together now), though. Any input appreciated. I didn't want to go massively radical on the build as I want it to do well on the street and on the strip.

Re: Projected build help
TTT for you.
How do you want to run the car? I see a lot of people building engines that run out of steam just over 5000. I like to run it to just over 6000. It will make more power and be better on the highway.
That's me. Your tastes may vary.
I wouldn't get involved with this "street car" "track car" thing, it's all about what you want to run.
A solid lifter motor will support higher RPMs than a roller, so I don't see why you wouldn't want to wind it even higher.
I'd like to know more about your goals before commenting. If your goals are good 1/4 mile time....spin it higher and go with the bigger cam. If you're stoplight to stoplight, that changes things.
I find a higher revving engine is more balanced. You can get it to behave the way you want on the street, but when on the highway have room to get to the top end.
Of course, the rear end gear needs to be taken into consideration too.

and excuse my typo error, I wasn't thinking.. I meant SOLID FLAT TAPPET. My motor is NOT a roller block.
