Spigot bush question ?

600hp max, its about the torque not the HP in my case so its fine. This the DF not the DFX, DFX is the super high one which goes up to 1200hp

I asked the guys at summit racing and thats what they suggested so thats what I went with

OK.............A good parts guy will tell you want you want to hear, plus they won't have to worry about there return policy

Doesn't bother me, it was a mid range clutch and one that was also recommended by bob harman motors over here. He's used the same one on similar spec engines, these clutches get an excellent review

Thing is rather over kill. A 454 clutch and pressure plate would do the same thing but for less money. But in the end your money your project

This is a 454 clutch......

GM original, oem, over the counter.

How you making out with the starter?

Dr_evil · Jan 15, 2014

Starter I'm fitting is the standard Cadillac one, the ring gear sits in the same position and the flywheel is the same size so I can use oem stuff for that. Starter is a tuff something, can't remember the name but it was only $96

+1 agree.

off subject slightly (as I do)
back in the day when racing, I`d make a bush out of anything I could lay my hands on, if that was mild steel/ silver steel/ ally/ copper or bronze I`d use that with a few thous clearance with a good dab of grease up the hole..
for its purpose it mattered not really,
even knew one team who just cut off the end of the shaft as it protruded past the clutch splines, as most clutches tend not to walk too far when disenguaged

in bangers, some were 1 meeting cars anyway, so the engine & gearboxes came out after the meeting, to be dropped into the next shell for the next meeting

best road car I ever done a clutch change on was the mk1 front wheel drive cavalier - the clutch shaft splines could be withdrawn into the gearbox allowing to drop the clutch out the bottom via a bolted on tin plate

it never made the mk2 later models - cost of producing the gearbox I guess..

I cant believe you go to uni and want to measure a shaft with a vernier

Seeing as you're working to a tolerance of +/- 0.01mm on measuring equipment can you not borrow a micrometer to check it? Be far more accurate than a vernier for work like this

I`ve seen men using mics as g clamps before now.
agree more acurate, but whe you get used to a good digital read out 8inch very - near

you can get quite close tolerences measured in any of its 3 functions.

nothing I made using them has not fallen from the skies yet...

FFS I hope not anyway..

Using a vernier to measure an internal (hole) diameter can be slightly inaccurate due to the very narrow flat surface on the vernier that touches the hole surface. Don't think it will make much of a difference in this case as we are talking fairly loose tolerances. If you need really accurate internal dimensions

then use a bore / cylinder gauge and micrometer.

+1 agree..

I used to have to use air gauges when doing magnesium gear boxes for RollsRoyce aero, as the bore limits were +/- in microns-----

but the air gauges were obviously made/and set using very very accurate setting rings..
but they were all fairly big bores, sort of 5 inches or so, but lots of them in each case half...

but for general measuring depths of drilled holes the tail end was good enough on a very near, and your point about internal measuring was a good comment, but as the bores I used it on were bigger than the OP spigot, so the flats of both nibs mattered less - I always mic`ed over them for tighter tollerences anyway for "general" measurements - i.e. setting up a boring head if it was`nt done on/by the tooling section..
blimey, just thinking about being back at work gives me a headache
