Im about to buy a GM847 for my lame 355. i have about 1000-1200 i want to spend on my cam swap, i want to be sure i get all good parts. what all should i get? i know im need a new timing chain set, im gonna get a new oil pump, i already have roller rockers but im not sure if they are 1.6's or what. i know i need new springs, pushrods and maybe lifters also. what else am i missing guys? if possible could someone make me a list and let me know where i should oreder this stuff it would be greatly appreciated!! thanks in advance!

 

also would i be able to keep my roller rockers that i have or should i ditch em and get new ones?

 

Do you know what kind of rockers, brand wise? Look at the rocker body they might have the ratio stamped on them. I would think they should be fine but hard to say will such little info.

 

Yeah i havent pulled the covers to look at them, they were installed when the motor was built right before i got the car. the work order didnt specify, it just says roller rockers. i guess i could pull one of the covers this afternoon and find out.

 

This exactly what has been done to my car..minus the mild head work.


8 1030 hyper pistons
1 set 1030 moly rings
overhaul gasket kit
3 piece timing set
8 std rod bearings
1 set std main bearings
1 oil pump
1 oil pump pick up
1 oil pump drive
1 police roller cam
1 set roller tip rockers
bore .030 over
polish crank
press work (pistons)
block prep
valve job #3


for a grand total of $2,066.95

now all of this was done back in febuary of 2001 at 74,000 miles, just last week i rolled over 100,000!!! it was a sad day...

I'd not get an oil pump as i see no reason to. I'd also make sure you get a good timing chain as i'd assume from the price of your rebuild you're running a stock chain. You need to get more info on the roller rockers.

 

Yeah they place who built the motor doesnt know...i still need to pull the valve covers and see if they are stamped or what not.
