Thread: Blower clearance question?

Tweet

Started clampin' stuff in place for the front suspension on the "Z" today

So, my question is can anybody tell me how much room I need to allow for a blower drive (Front of the block to front of the lower pulley)?. I'm figuring 2 pulleys behind the blower drive just to be safe. If I go with 1 belt at least measuring for 2 I'll know I have room. I have about 4" room in this picture but the block is already set back an inch. I've got the rack about as far forward as I can go. I'm making my own firewall, so my only setback limitation is the blower against the windshield glass

Closer shot of the clearance I have. 4" .....A belt is 3". I'm guessing I' need 5.5'' to 6.5" to clear the raack & still have room to get a belt on & off ????
Height wise the block will set about where it's at or possibly 1" to 1.5" lower.

pro, i think youll need 4" to 4.5" from the tip of the crankshaft. looks like you have 4.5 from the block. i dont have anything to go by right now but far as i know the belt pulley will be flush with the end of the crank and then the 3" blower pulley will bolt to that

I'm close, little more rearranging is in order.

I answered my own question.......
7.875" from the front of the block to the front of the pulley. Add an additional .7" for each accesory pulley.

7.875 - 7.876, whatever it takes to get the job done. I was gonna say to add .7" for each pulley too but you beat me to it.

Ya know, I was gonna say 7.8749, but I felt that would have been a bit too tight. Ya wouldn't want any little squeeks in the engine area, it's anoyin.

The belt is only .250" thick, if that. How much room do you want to give it.

Jus' what I need ........... I'm not greedy. He HE HE

Hey Pro, does this mean you don't want to use my Big Block Blue Oval stroker motor I have setting in the shop??? C'mon man, nobody likes us pro-street builders anyhow, might as well get some Blue Oval power under the hood and P*** off anybody you might have missed!!!!! Tee Hee Hee

Did I tell ya about the '85 Vette I wanna put the Windsor stroker motor, 5 speed, and tube chassis into????

Blue oval in the "Z" ..................... now yer' scarin' me Dave............

I'll make er' fit. That's what they made torches for . right???

Geez Pro, I ain't scary. If I was, that was years ago and I've mellowed. Don't believe all the stories ya here.

Besides, it would be better to finish the car, make some passes and get the car sorted out so it hooks hard and goes straight, then we could apply a large dose of Blue Oval Thundering Big Horses and ya could really go fast!!!

If yer friends didn't mess with ya, who would??? Tee Hee Hee
