I`m not sure what size my engine is,I can`t see the casting numbers on the back of the block but here are the engine numbers off the front VO223CFK 7CN777826 any help would be appreciated guys

 

1982 crossfire injected 305 from a z-28 t/a or impala 165 HP twin tb's (kinda makes sense since its a ceasefire car).. the second numder is part of the vin of the origional vehicle... VO223CFK V- Flint Mich. Plant, 02 Febuary, 23, 23rd day of the month the other info is the suffix code info CFK...

 

thanks! the car seems to go so well,& most people on here seem to diss the 305 I thought it might be a 350! The engine was in the car when I bought it & yes its an 82 Z28. You say it would develope 165 hp its had a few mods done, any idea what it would put out? it has a holley600 v/s carb,an edelbrock performer inlet,mallory dual point distributor (with a petronix electronic ign. kit fitted),msd coil,headman headers.As I said it goes like stink (after an initial hesitant pause,which,thanks to a lot of help from the guys on here,I will be sorting soon).

 

eh just a stab in the dark but with headers and full exhaust i'd expect 15-20 hp or so.. if you have the origional cam that would be your main weak point.. 305's arnt a bad engine IMO they just get a bad wrap because you can build a 350 for the same price and make more power.. still fun as hell to embarass guys with stock 350s with though.. specially if u can find an early 80's crossfire vette.. walk all over it with ur carbed 305 n then smile at him

 

thanks! what cam would you suggest? any other worth while mods?I got it at this stage of tune so I might as well tune it a bit!!!!!

 

I've heard of people using the http://www.compcams.com/information/...umber=12-249-4 and doing pretty good with it.. never really modded a 305 too much myself.. do you know what your rear end gear ratio is? i noticed its stick so you dont havta worry about a converter... might want somethin with a little more duration.. maybe someone else will chime in.... you'd probably find better info if you make a new thread for a cam suggestion... as far as other suggestions a dual snorkel air cleaner setup from a H.O car would probably help ya out a little with a good high flow air filter like a k&n... anything to help it breathe better basically..
