Ditto what Brent asked.

Also, did you check out the 2287 P Piston thread just below? As noted, several stockish pistons have exhaust valve pockets that are right on the edge of hitting with a cam that big. I had to grind all 8 of mine in that area and looks like (gt350hr?) bent a valve cuz they hit.

The comet is really under 3000 lb??? Wow! bore/stroke/rods, headers, exhaust, carb?
That way I can Gonkulate it.

Any dragstrip time? That's the only way to really know if it's running like it should be.

The thing with a bigger cam is, sure you could always do better, but if you have a good flat tappet already broken in & happy, its a lot of work to do much better, like roller territory and then MORE valve-to-piston checking, may even have to pull the motor just to make the cam clear. Yuck. Unless you enjoy that of course!

Where does it feel like it peaks the horsepower?  Wanting to stay flat tappet or wanting to switch to a roller?  Have power brakes?

Not trying to bust your chops, but if you get that car onto some certified scales, I'm bettin' your estimate is about 400-500 lbs low. Scrapyard, truck scale, race track, spend 5 or 10 dollars and know for sure. Tell us what you get. I'm not shooting in the dark here, my friend.

I weighed my 67 Fairlane GTA a while back, kind of an oddball GTA. Bucket seats, no console, column shift, orig. H code 390, now 427 2 x 4 MR, C6, 1/2 tank of fuel, 3450 lbs on a certified scale.

no power brakes.it got up on the rev limiter at 7000 in a burnout.not sure where it peaks,but it hit 7000 . i got my weight at a local scrap yard.it could have been wrong but i parked on the scales and got out of the car.i have fiberglass hood and fenders no cage,alu heads,intake,water pump,no console,no tools in car,no back seat.scales could have been off a little,recycle place are ripoffs,maybe there scales are set low,i dont know but im not going to argue over it without knowing for sure.

If you want to stay hydraulic, I don't think I can help you much.  If you want to go solid, I could pick you up some ponies.

OK your car is in the Gonkulator, which is not as much fun nor as definitive as a timeslip, but its free anyway and no broken parts.
The "G" says
Torq 546 at 4000
Powr 502 at 5400
I start with an all-iron Fairlane at 3550, an all-iron Comet at 3580, full of gas, spare, jack. But that's a lot of weight you took out.
I guessed the car weight at 3200-3250, call it 3400 down the track.
1.79
7.67 at 91.8
11.95 at 114.9
That's shifting at 5800. Shifting the Gonkulator at 6000 gave the same.
I kinda agree w Brent, not sure how much more you can do with a hydraulic cam.
Retarding this cam 4 degrees to straight up lost 6 ftlb and gained 3hp, not worth it.

I assumed 3" exhaust. Running open headers, like the GOOD old days at the Dirty "D", Gonked to
11.72 at 117.5
Not much gain but it sure sounds good.
The main reason I think for open headers today, beyond the free educational experience in American History you are providing for society, is it lets you tune collectors. I'm not sure what headers you have, I guessed the FPA's that Jay used in most of his TGFEIC dyno runs. Those don't seem real sensitive to collector length with your engine, but again that's an easy thing to try.

Ditch the fan for an electric fan, Gonks to
11.64 at 118.9
Well that's 3 tenths quicker without even changing the cam. Have you had it to the strip yet? (Good place to weigh it too, they have to be pretty accurate)
