Default Stage II ....... what do you think?

I finally received parts that I've ordered to complete stage II modifications
as I planed.

What HP numbers should I expect with this mods?
( stage I mods are in sig. )

Here are the parts:

- LPE 74219 cam
- comp cams valve springs
- LPE titanium retainers
- hooker supercomp headers
- Accel adjust. fuel press. reg.
- comp cams double roller timing chain set
- I will also do some serious heads porting and polishing

I think your potential gain is about 70hp.

Add some 1.6 rockers on there as well...but it seems that your limiting factor now is going to be the TPI intake. Are you going to do any work on the runners to try to increase flow?

I have allready ported stock TPI as much as it can go. I have also siamesed
plenum and I'm thinking of siamesing intake base at this point.

1.6 RR and Superram should be stage III next year if everything will be O.K.
