SPF Trans/Clutch Swap
I just purchased a Superformance.
Can the transmission be moved back allowing enough clearance to remove the McCleod shield and replace the clutch and instal an AL flywheel ?? This is an earlier 2001 model. For next season, I was also considering a swap from TKO 500 to the Tremec 600. I was told seats must come out, rugs off and trans tunnel cover must come off to remove the TKO. Uugh....maybe it's best to get it all done in one felled swoop ? Any advice or assistance is appreciated . Tx Jam |
Yep, you're going to have pull the trans out through the interior in order to change any of the above. Not
real difficult. Just make sure you have a lift or a strong buddy to lift the trans out of the interior. Do a search for step by step instructions. Or join scof and their site will walk you through. |
Pulling the seats and tunnel will take far less time than trying to snake stuff out without doing so. Before you pull the tunnel either remove the carpets (glued down but can be removed) of cover them with Road Wrap. The sealer on the tunnel to floor is stringy, nasty stuff that you don't want to try to remove from your carpets. We use the Road Wrap Protective Film : New Car Paint Protection : Paint Protector : Automobile Paint Protection : BuyRoadWrap.com

You can do it through the tunnel or you can stab the engine and trans and do it outside the car. Sometimes its difficult to get the trans shaft in there so I just pulled the whole thing out. It may take a little more time but not as much as you think.

Thanks guys....I will go from inside and just swap the tranny for the 600....DONE !
I also just noticed the slave cylinder had a bit of leakage as I removed the boot seal. Plus it only pushes out about 1/3 it's cylinder travel. If needed...where the heck do I locate a slave cylinder ? |
Forte has them, speedway motors sell them, summit..

Thanks again guys.....I am thinking of the .064 OD tranny...the motor has good low end torque. I also have a napa about a mile from my house !

Yikes....I have a .068 OD in my Tremec and it feels fine at 60-65mph...the difference to .064 is something to consider !
Went on Summit last night but I think I need to get under the car again to match the right slave cylinder. |
FWIW I'm running the 0.82 fifth with 17" rims and 3.07 rear gears behind a big block that's bored and stroked out to 450 cubes. At 70 MPH cruise I'm turning about 2200 RPM. Wind noise and exhaust noise are just about even. Very happy with this combination.

Don.....
I just took out a calculator .... Are my numbers messed up ? I had 327's in the car with the Tremec 500 .68 OD Using a calcualtor just to compare ratios: 3.27 x .68 = 2.223 Now I still have the Tremec 500 but went back with the original SPF 373's . 3.73 x .68 = 2.536. You mentioned you have 3.08 x .82 = 2.525 Assuming we both have the same 27" tall wheels ( I know you have 17' rims) that makes our current combos very similar ! In keeping the 3.73 rear gears ...if I bought the Tremec 600 with .64 OD that would be: 3.73 x .64 = 2.387 That's actually steeper than when I had the 327's but not as steep as what am now running ! |
Thanks Jim.....I agree on the gearing especially since I have the steeper 3.73's.
I will match up the slave this morning. |
this is fun to play around with.......Tech Tips

Here is a great site with all kinds of automotive calculators.

Hah ! Hey John Hall....I have the Wallace link in my favorites and have refeered to it many times especially last year when I bought my GT500 ! Thanks Bud !
Thanks boys for all your help. As we all know we are individuals with individual preferences. I have learned a lot from this thread ! Today I ordered the Tremec 600 and based on the motor making 450ft.lbs at 2800RPM decided on the .64OD . Thanks to Mike Forte's guidance I also ordered a RAM clutch & Ford Racing AL flywheel. I am looking forward to how she runs with the 373's.....and the long 2.87 first gear . All advice was much appreciated...............Jam |
