The HP peak will be a lot further up the rpm range; try 5800rpm. The TFS top end kit together with a full set of bolt-ons and a tune is capable of ~320rwhp, which is ~100rwhp more than you have now.

Wow, I didn't know the gains would be that great! I has thinking about piecing together GT40 heads, a cam, and a intake - but I might just save up for a top end kit.
Nothing wrong with the TFS kit but I'd consider piecing together your own. Try andersons, they have quite a few options and will Also help you put together a custom one

does the track heat kit come with the stage 2 cam? if it does I'd guess 330rwhp, peak rpm at 6,400.
Peak hp with the stage 1 cam kit will be around 5,400-5,500 rpm. Thats where mine peaked when I had it years ago. Stage 2 cam with a track heat will be around 5,800 and 310hp at most.
Pick better parts. The heads are fine, but there are better manifolds and camshafts. 300hp now-a-days is weak, slow and uncompetitive

only 310rwhp? Id think it'd be way higher, I have systemax kit with Z cam (compared to TF kit-better intake,worse heads, cam IDK) and I have 325rwhp, Id think trickflow set-up would be equal at least.

I did sound a wee bit gay there.
between 300 - 330 is about all you can get with a 302 NA without going higher CR, solid roller, or carbed.

300rwhp is definatly not weak in a 3k car, most ricer cars weigh close to that and have like half that power, and somehow the owners think they're fast, haha

yeah i have 325 with crappy holley heads, sure I could hit 350 easy with a set of afr's and custom cam

you got any track times? what are you revving to? mustang dyno? what is the combo?

350 is a hell of alot to ask out of a 302 NA it's not just throw in a custom cam and be done you have to have the perfect combo to even sniff 350's door.
hell a trick flow top end kit on a 331 struggles to get 350 to the ground.
No track times yet. I just finished the motor last month and had it dyno tuned. The dyno was a dynojet. Combo is
Fox Lake stg2 ported brodix heads and systemax intake
comp xe276 cam
bbk 1-5/8 lt and h pipe
Electric Fan
accufab (race) 75mm tb w/ 90mm inlet
77 prom
24#injectors
410 gear
Anderson Ford 4 inch power pipe
t-5
UDP
The motor makes peak hp at 5900 rpm and holds to 6100' Peak tq is 4600 rpms.
Still has a/c and ps..

thats a nice setup hows the street manners with that cam? also not trying to put down your combo or say u didn't make the power but i would like to see some track numbers on this car.
I had a similiar combo 5 years ago using tw heads and the same cam in a 89 coupe. The car made 359 also and it ran 7.40's @ 94 in the 1/8. I have no doubts this car a will run low 12's maybe high 11's on drag radials. I do not have a drag suspension just bbk lowering springs. My goal was to make this a fun little street car. As for drivability, it will buck alittle below 1800 rpms. other than that its fine.

with 350 hp with marginal weight (3100 - 3200) u should be running 11.5s 11.6's at 115+ mph thats why i say i don't see a 302 NA doing that.
