awesome lets us know how it turns out.

 

Forget the gear drive it is a waste of money and get the Air Gap intake.

 

+1:thumbsup:

 

If you like the noise of a gear drive it is your money. I would go with the air gap. It picks the runners up off the hot engine which equals HP when the engine is hot. On a dyno it don't make power but in the real world it helps to keep you from losing HP.

 

Ask 70_Fastback about gear drives...it won't be pretty!

 

:thumbsup:

You ought to see the pictures of the destruction when his gear drive failed. Unless you're trying to impress the Chevy guys, gear drive is a waste on the street. I run a 550-600hp 393w with a double roller chain and I have no issues.

 

Yeah, I would not waste my money on a gear drive for a street car with this little hp. They are noisy to boot. If its got an Edelbrock RPM intake you don't have to spend the extra money on the Air Gap if you don't want to. The Air Gap is better technology but won't make much difference on your engines hp and rpm level.

The only thing I worry about when I see crate engines priced this low is what is the workmanship and the extent of the machining and what is the quality of the parts going into the engine. Sounds like you have done some homework on the company so I hope everything turns out well. Let us know how it runs once you get it in the car!

 

Some people like to hear the gear drives, not me though. To each his own.

 

+4 on picking the Air Gap over the gear drive. They may make a cute whiney sound, but they generate excess heat to boot.

 

I never even considered the heat generation of a gear drive......any data on that...just asking.

 

another for air gap intake instead of gear drive , spend your $$ on go fast parts .

 

i bought some parts for my 68 f100 390 from tuff dawg , real nice guys , lots of knowledge on the FE motors .

 

Belt drive!!! OK, just kidding.

 

Haha, but it would take care of a lot of noise issues with both, gear drive and double rollers.

 

A good double roller chain is all you need for a street or even a mild race engine. Ditto on the Air Gap. Got it on mine too!

 

Thanks for the replies. I was actually thinking of dumping the gear drive but I'm not sure about the Performer Air Gap. Will the air gap fit under my stock hood? The gear drive I just wanted for the noise anyway, but I really think I would get sick of hearing it after awhile. If I'm not going to have any fitment problems with the hood, then I'll probably go with the air gap. The only reason they talked me out of the air gap was because they don't think it will fit under the stock hood. Anybody running air gaps on 67-68 Mustangs??

 

Yep, I ran an air-gap on my '68 with a 351, so it will definitely work with a 302.

 

Thanks :thumbsup:

 

I have an air gap on my 347 on my stock hood 67 coupe. I used a drop base air filter just to be safe.

 

I noticed you said that you request a Thumpr cam. You may have, but make sure you listen to one of these in person and not just internet clips. I bought one because I loved the sound on youtube but was never really happy with it once I installed it. The clips do not capture how noisy the valve train is. My car sounded like a diesel under the hood there was so much valve clacking. The cam also requires a lot of initial timing (18*) and makes carb tuning a real pain in the rear with the long duration.

 

I'll keep that in mind. Thanks

 

Awesome...looking forward to seeing how it turns out. I've been wanting Tuff Dawg since I bought the mustang as a project. Really affordable crate motors but cheap is not always good. Let us know! Maybe post a video

 

Hopefully by June it'll be running. I'll post a vid then

 

First off - very nice price for a crate motor. I just picked mine up on Friday after installation (it's a little more pricy but lovin it).

There's much proof out there that the Air Gap beats Victor Jr., and all others for mid-range & upper hp/tq numbers (motor runs cooler) - and it will give you much more than 4hp. Spend the extra money.

Here's a cool dyno test result:

Thanks for the youtube vid. My mind is definitely made up. :thumbsup:

Ummm...where? I think you need to back this statement up with proof. An Air Gap is going to make better low-mid range torque on a dyno but that doesn't mean the car is going to be faster. I want to see this "proof".

 

This

 

I nixed the decision on the gear drive and also told them I'd prefer the Performer air gap over the Performer RPM. Hopefully I'll see this engine deliverd to my house in 5 weeks.

 

I think that, that was a good decision. Good luck with your engine!

 

Thanks :thumbsup:

 

I was thinking about going with Tuff Dawg crate engines. Hopefully everything turns out great.

 

Bookmarked this thread! I am thinking about ordering the exact same engine from Tuff Dawg, so I am extremely interested in your results. Good luck and keep us posted!

 

Hopefully I can get a vid up when everything is installed. That probably won't be until mid-May or later. I'll make sure I keep you guys posted.

 

I spent more tracking down an old roller and rebuilding it than that, and after some of the headaches I've been through, I'll go crate next time! Keep us posted. I looked at those guys when I bought a 351 for another car, but ended up going another route.

 

Keep us posted Jays seems like lots of ppl here interested in these motors. RWHP dyno numbers if possible
