What gears would you say would help my combo out the most.I'm looking to go faster in 1/4 and not has worried about daily driving.Althogh the track is 1hour away so it needs to able to make there.I was thinking of 3:80to4:11.And would you do gears 1st or a posi type unit 1st.Cant afford both now.Or should I just start looking for a 9" and dump the 8".------------------

Ron,
Sounds like you've got a sweet package there!
Depending on what your cash flow is and what level of performance you eventually want will determine which way to go now. For instance, if your plan is to eventually build this into a Street-Stormer or Racer, then I'd recommend you start shopping for a 9" rearend - it's a much stronger piece and parts are more available than for a 8". But if this is your only car and you need to drive it everywhere / everyday, then I'd locate an 8" traction-lock differential for sure, and step up to a 3:50 or more gear to get you into your engine's power band. Good Luck! Ryan

Give us a little info on your cam specs, tire& wheel size, and your current 1/4 mile baseline..Unless your 351W is anemic, I would say that you are already smoking the back tires at the touch of the throttle..Since you're running 2.80 gear, open differential, and a stock converter, you can start by upgrading to some traction devices. Anything above 3.25 gear will just make traction matters worse.. I would say a 9" posi rear, good traction bars, and a stall converter would be good for starters. Your gear selection will depend on what rpm range the engine likes to pull and whether or not you're going to stay with the 8" rear.. My original 8" rear started loosening up fast when I started hitting it hard at the track and I didn't want to spend any money on a cheapo 8" rearend, so I went shopping for a 9".

Ron,Locate a narrow 9" housing from a 57-58 Ford or Edsel wagon, and find a center section from an early Bronco w/4.11 gears and trac-lock. It's the easiest and cheapest way to go. The 4.11 gear will be perfect up to about 112mph in the quarter at 6000 rpm. If your stock 351 won't pull 6000, then it'll still top out at it's rpm peak. Maybe 100 mph @ 5200 rpm or so. The gears will grow with the engine in other words. SteveW

Thanks all I can tell already this is the site for me.66351stang.The heddmen headers bolt right in.I had a local exhuast shop do the rest.I have 2-1/4 pipe with an H-pipe and turn donws at the axle with 3chamber flowmasters.The shop had no problems with the collectors lining up.And the turn downs look sweat from behind the car.About gears my car is not my only driver its just for fun.I'll keep on making more into a street strip car all I can the faster the better.But power is only good if I can get it to hookup.I'm not into the burn out thing.I just want it to go while the other guy is burning them off.Most my racing will be done on the street.And yes it's TOPGUN at Fallon raceway.Have not had this car out there yet.Thanks agian and keep it coming.Ron

ponycar,I'd run 2 1/2" exhaust, at least 2 1/4". Have a freind that put a new 430 hp chevy crate 350 in his '67 camaro and his 1/4 mile mph and et did not improve over his old 327! Then we had a w/e race where he was allowed to run open headers, and the car jumped 8 mph in the 1/4 mile over his 2" dual exhaust. He's installing a 2 1/2" exhaust system now. SteveW

I second the 2.5 or 2.25 pipes fords need all the help they can get on the exhuast side.I'd also do an H-pipe or X-pipe on it too.------------------

Ron,In the old days (early '70s) we street raced on Edison Way. It was nicely lit and had the 1/4 mi marked off. Is it still that way? SteveW

Thats great Steve I too remember Edison way and no it's not the same.The road is run down still has the lights.And it has fadded marks on it.They have three differant area's now that they race on.The 70's were great for street racing the fines were not has big and the cops were not as fast to get there.I mainly race were ever I can find some one to race.To scared of getting a ticket.Thats cool that you remember Edisonway.I'm 36 now so I remember the late 70's on in to the 80's.Which was all BFR.[BEFORE RICERS]Ron.------------------

forget the 8" ...with a 351 you are dumping money down the toilet on something you'll later break.A 9" or adapting a late model 8.8 are better bets.
