Re: Edelbrock E-Street cylinder heads

I think your assuption is correct! I'm running Twisted Wedge heads on my SBF (street/strip Mustang), and before I ever installed the heads, I replaced all the studs (with ARP), springs & retainers (Comp Cams) with better quality units. Even though you are spinning 3000rpm where I'm spinning 7000, I ...

Re: 350 - Best box

Most folks I know running stock/near stock 350s, run a 2:1 box, with a 2 blade R series prop. That being said, what prop do you currently have? My opinion is you would be better off with the 2:09 Stinger, but again, depends on what prop you are turning???

Re: 351w carb tuning

Probably not much help, but it should run fine on that carb. We run a Holley 670 vacuum secondary carb on my Son's DD. His timing is set at 34*, 70" Q series prop, turns 2800 - 2900, and it runs great.

Re: Need help figurung out what egine I have

They usually have a data plate mounted to the case in front of the right side mag (left side if you are standing behind the boat looking at the prop), if the data plate is still there, it will tell you what model and what HP at what RPM?

Re: first airboat

should i keep quick slip or polly the boat Again, that all depends on what you use it for. If you don't plan on running much dry ground, slick bottom is fine. The more dry you run, the more often you will have to reapply the slick bottom, and slick bottom does nothing to protect you hull. If you pl...

Re: Airboat fuel question???

Need more info, how is it mounted? Electric fuel pumps are designed to push fuel, not draw it from the tank. The closer to the tank you can mount it the better. Does the tank have a pickup tube that draws from the top, or is the outlet mounted low (gravity fed). I run a Carter on one boat (car motor...

Looks like a great little boat, should serve your purpose well. If your future plans are just riding with your wife, it may be all the boat you'll ever need. Would be a nice frogging boat also.

Re: Gear Box or Not

What prop is on it now? If it was a 350ci, I would suggest a 70" Q prop, and keep the rigging light and it would run the hill ok. Being a 305ci, I would venture to say a gear reduction of 2:1 and a 78" - 80" 2 blade would be needed at a minimum for it to perform anywhere near what you want it to do.

Re: Air filter size

We run a "Cadillac batwing" style cleaner on my Son's small block. Should he get caught in the rain, he can just spin the air cleaner 180 degrees so the intake duct faces the back. Not the best setup, but works fine.
