blowen 253?

[EFFDUP]

ive got my hands on a 3/71 blower with 4 barrel adapter and all the pulleys, would this suit my 253 with 308 heads or would i destroy the motor? ive heard the crank could snap easily? would i be able to just bolt it on or to much money and work involved? cheers

[ari666]

I've turbo'ed stock 253 and 308 engine no worries, stay sensible and good tuning, retension the cylinder heads before you start.

[Pub247]

3x71 = 213ci smaller than your motor capacity but it still might work if you overdrive the #### out of it

[EFFDUP]

it was running on a 350chev, not sure if its overdriven or under is there a way to tell?
it cost me 500 all up was just thinking of doing it for a bit of fun but dont wana go blowing my crank or anything

[Hangman]

You'd be doing well to snap a crank, I'd imagine something else would give first.

[ari666]

dont wana go blowing my crank or anything

why? cos' 253 cranks are so damn expensive?

lol, just stick it on. if you blow it up, save 5 dollars and get a new 253

[EFFDUP]

what other damage can i do? does the carb need to be anything special or can i use my 600 holley?

[4wheelinls1]

Nuthin if you draw through, you will need to manage the ignition timing, boost retard.

Listen to ari!!!!

[EFFDUP]

just tried fitting it all up, gona take alot of work to make it fit, the blower needs to come forward about 2inches, might just flick it off, i also have power steering which wont work there will be no room. BUGGER

[ari666]

dude. SELL ME THAT BLOWER!!!!!

(pretty please) i have a SBC itll bolt right onto easy as pie.

[4wheelinls1]

On a Buget, weld up the mechanical advance, start around 15 degrees static (also total) and fit the blower.

have been offered a swap for a tunnel ram setup for 308, is this worth a straight swap?

[EFFDUP]

3/71 blower with 350chev manifold and all the pulleys FOR a cain tunnel ram with 2 450 holleys
does this sound like a resonable swap? or should i hold on to my blower?

[DANNY8]

I'd go the tunnel ram...that's just me tho. Rekon those manifolds go for about $1000-$1500, sometimes can find them cheaper if ur lucky.

[ari666]

whereas a blower will cost you 4 grand...

[383 hatch]

I'd mabye swap the blower set up for a DECENT manifold and carb (if the blower definately won't fit that is), unfortunately, a tunnel ram isn't a decent manifold (for a street car). If you're going to have a hole in your bonnet, make it for a blower.

[EFFDUP]

i am still trying to have a crack at fitting this blower, the crank pulley is not gona fit at all could i use a gilmer drive pulley on the crank or are they completley differant?

[ari666]

you just need to get a snout for it. what brand is it? part number?

[EFFDUP]

i can make a spacer for the snout thats ok, just the pulley for the crank isnt gona fit (its off a chev) was thinking of just using a gilmer pulley on the crank

[ari666]

??? is it a V-pully, serpentine? i dont understand. swapping the pulley would be easy. gilmers are commonly used, but i dunno where you would get one that length though. itd have to do the crank, alternator and PWR steering. itd have to be huge. maybe look into a later model serpentine belt?

[EFFDUP]

i can use the gilmer power steer part for the alt,crank,water pump just wondering if i can use the bigger part as my blower pulley on the crank?
does anybody know the size of the gilmer pulley thanks
