You'll need to talk to a machine shop, for a price.

still aint gonna beat me man!!

just u wait clown..........i will suck u down my carby....grind u threw my engine and spit u out the back with a great big paaaaaaaaaaaaaaaaah!!

Even B4 you could do any of that i wouldve boosted past your arse like a **** storm CLOWN.

If youve had your heads done already man forget bigger valves,its a 253 and big valve 308 heads are gunna be a waste,stop now or get a 308 or310 stroker kit and nitris oxcide,3.45 diff and tuffend trimatic.The one tunna will do circles.

i couldn't be bothed reading everyones post so i dont know if this has been said so. put vn heads on it witha 600dp with a 265crane cam i think thats what is called im drunk so i cant remember beucase my torana is making 206rwkw with that and more but i cant be bothed typing it if you want to know what i have pm me and i'll tell you catch ya Some original photos have not been recovered yet.

so guys wat u think........img gonna stick a blower on my 253 :P

i think sell the 253 immediately and build a 308 up, same $$ for lot more power and torque! put vn heads on a 308, big solid cam, harrop manifold and a 750 holley or something and you'll run 11's

i know i know..........im just doing this to prove a mate wrong.....when this pig gets over 300 hp i will drive the engine for a bit then find a good 308 and put all my parts in it and then put the vnheads on

dont just spend thousands of dollars to prove a mate wrong. Its easily possible a guy on sc forums just made 187rwkw with one, the 253 commodore cup cars had 230kw motors too. Problem is to get it to make that sorta power u need a fat cam with big duration and as such that means something that will be **** down low and have real crap throttle response which means big converters and short gears e.t.c, defeats the purpose of a street car really.

ive already spent a grand on it chief all i have to do is chuck it back in

so guys i stuck my donk on the engine dyno the other day.....she pulled out 330hp!!!!!!!!!!!!!! before throwing a valve cause the person i sent them to did not seat them properly

Got a copy of the dyno sheet? If so post it up..

Was there and witnessed it fellas!!!!! Wat a ****en noise it made as well when the valve dropped!! LOL. Yep 330hp at 6000rpm or thereabouts.

yeh i got 2 copies actually but i don't have a scanne bit i gurantee when i get one i will put it up just to show off.....LOL

hey guuys i have thought bout it and im gonna supercharge my donk......wat do i need to be able to tdo this and where would i go to get info in this

Will depend on what s/c ya gunna use.

well ya see im not sure on wat kind of superchager wat dou think would be best for it?

330hp from a 253?! wow.. well forget supercharging, it is no doubt a very healthy motor with a big cam and a lot of compression, and high compression and superchargers AND pump fuel dont mix. Unless u were going to run it on avgas or mathanol

A Mr Gasket under bonnet blow would be fine?? GM 6/71 would be pushing it!! But talk to the pro's, as you are talking big money, and there are allot of different set up's out there. But I'm a bit with Sinister, 330HP is very healthy from a 253, so listening to back yard guys could see that turn in to a hand grenade, with one wrong move. The guy you want to talk to is (ummm ok he drives a yellow corvett in top door slammer) "Pain" but its not spelt like that.
