I am currently building a 355 and I am expecting to pick up my block very soon and need to decide on H/C choices. My question is the Le3 set-up to big for a street driven 355 I am looking to turn the motor to about 6800rpm and have it dyno tuned.

My build consist of
Zero Decked block
Mahle forged -5cc flattop pistons for 6" rods
Scat forged 6" I-beams
stock polished crank
Internal balanced
1.6RRS
EWP
Hooker LTs no cat or any emissions
A4 with 3600 stall and 3.73 gears in the back.
36# injectors
58mm TB
Intake work to match heads.

 

so....what are your questions?

 

No, it's not too big for a street driven car.

Go with 4.10 / 4.11's with an LE3... 3.73 is not enough gear (IMO).

 

Thx that answers that i guess I will have to go with a LE2/Le3 cam kind of set-up

 

Did you mean LE2 cam, LE3 heads? It's the cam that determines how much gear you need. You might ask Lloyd for a H/C combination that fits your setup and desires. There are quite a few LE cams for specific applications.

Good luck.
