I'm about 2 get a cam re-grind for my 3k its got a 40doce weber sidedraft extractors and a 2" exhaust I'm thinking

about getting a tighe cams 474, i want maximum lumpy idle as the car is only used on the weekends, has any one

used this grind cam on the street?

nope, but i will be interested to see how it goes in terms of street drivability

hey, theres a ke70 on youtube with a MASS cam and i was talking to him, his was a custom grind but he said the 413 tighe cam was pretty close to his grind...

The engine is a 5K, thats running 7.8:1 comp also so with bigger comp and carbies it sounds mad.

 

Biggest Cosworth grind available.

 

.420" Lift

 

50/86 316 degrees duration.

my mind is made up thanks to the input on this I'm going to go with a camtech cams CT003 615 should sound pretty mean thanks guys!

rotoresque!

And a pig to drive to boot!

 

Rough idle, strong top end, competition engines only. Min 12:1 comp ratio.

 

I'm guessing your motor is definitely not a competition engine (or you'd be looking for a cam with the characteristics you want, not just a gay idle) and I'm 99.9999% certain you wont be running anywhere NEAR 12:1 compression ratio.

 

 

I give it a month and you'll be looking for a stock cam.

I hope hes not just putting a big cam into a stock motor.

 

Sure it will idle lumpy but thats about all.

Certainly looks that way.

as i said my car is to only be used on the weekends all i want is a lumpy idle I'm not after a performance increase it is a 3k after all.

if you guys know of a cam grind that offers maximum lumpy idle and is still streetable on around 9.5:1 compression let me know???

Lighten flywheel, remove clutch fan and run something around 290 degrees duration. Should see some excellent lump while remaining streetable.
