351C Stroker / TKO 600 bellhousing question
#1
I am in the middle of stroking my engine to 408 plus mods and installing a TKO600. I expect my engine to be producing between 450 to 500hp. I am purchasing most of the parts to install the TKO600 from Modern Driveline - they offer a very complete kit. One of the questions that has come up is the use of the aluminum (MD-401-1401) or steel bellhousing (MD-401-6060). According to them I am right at the point where I may need the steel bellhousing. However, the QuickTime bellhousing is about $350 more than their aluminum billet. Does any of you have experience or any insight that can help with my decision? Is there a risk at higher horsepower for the clutch/flywheel to fail and go though the bellhousing? The end plan is to run fat street tires with a locker, so not all the power will be able to be transferred to the ground.

I'll be running a 408w with approx 500 hp and an upgraded tremec 3550. I'm doing the cable conversion and a Lakewood bell housing. I also have an aluminum bellhousing in case the headers don't clear the Lakewood. I did spring for an sfi flywheel. Personally I'd do the steel for sake of mind if funds allow.

I have looked into this myself. I am also going to run a tko600. I have a mcleod extreme street clutch kit with a hydraulic clutch setup. I will be running a 438 clevor with about 650hp and 600 ft lbs tq. I'll be using a bellhousing out of a 92 mustang 5.0. A lot of guys on fox body chat rooms are also using stock bellhousing with turbo setups. A steel scatter shield bellhousing is a must if you plan on racing the car on a regular basis and/or spinning above 6500rpm. Even then, as long as you use a top quality clutch set and a billet flywheel, I don't see any reason why a stock bellhousing won't work on a street car. Just my .02

6,000 rpm isn't anything crazy. I'd just go with the aluminum one.

Tony, are you using a 157 or 164 tooth flywheel?

The 157 is much more common. I resurfaced and reused my 164 tooth, here's the only bellhousing available for a 164 tooth, QT does not have one to fit...

Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic! thumb

it is important that the bell housing be dialed in. lakewood has a dowel hole relocation kit. robb mc makes some trick dowel pins. other offset pins are available from summit etc.

After much thought I decided to go with the QuickTime bell housing. Yes, it is more expensive, but I am not going to worry about it whenever I push the car to the limits. The Lakewood alternative was a few bucks cheaper but weighing 40 lbs. The QuickTime weighs 20 lbs.
Thank you for all the replies.
