Found an l67 at the local yard. Going to get the hd tranny to. 30k on it. I also got all leather seats since my ss didnt come with them. I need a list of parts for the swap

 

If you found a l67 complete motor you have everything you need. Your going to want a bigger pulley tho if your using your bottom end unless you add like headers, cai, etc...

 

What 04ss/sc said is all true but if I remember correct you will need a few wiring harness adapters from Zzp to complete it. Also font waste your money on the HD trans, only difference between a HD trans and a non HD trans is gearing and differential. The HD diff can be easily swapped into your non HD trans and the gearing in a non HD trans is higher than a HD trans which is better IMO.

 

Alright cool thanks. Probubly cheaper to buy the motor or buy just the peices I need?

 

If you've got a complete L67 drive train, why not just swap engines. Would simplify things a bit and you'll get some more power over a top swap.

 

Actually a top swap on a NA engine with supporting mods will make more HP then a regular l67 engine because compression is higher.

 

Thought you were getting rid of the monte? Im confused....

 

Ya high compression that's why I said you will need larger pulley unless you have intake/exhaust and plugs at minimum. And I'll have to check on the gear ratio think hd had 2.93 or something like that and min was 2.7 idr ill look

 

HD trans gearning is 2.93 and standard trans is 3.29

 

no need to get ZZP's wire harness. the map sensors are different just get that connector and sensor. if you are going to tune it as if it were a L67 then the BBV solenoid and harness are needed (unless you delete these) the l36 pcm file does not need them.

if your top swapping you will need:
-everything from the Heads up. heads, LIM, SC, valve covers, injectors, fuel rail, TB
-coil bracket/engine mount
-idle stand off pulley that mounts to the block
-harmonic balancer off the l67
