Series One NA potential
I just thinking, what is a realistic HP number that a NA can achieve with the mods that Jr.Day or anyone else has come across.
Now Im not talikng wild mods, but something to get the car into Series Two */C range (doable?)
Im assuming Cam, rockers, springs?? anything else??
SO what kind of numbers are expected and what parts are required to achieve them??

Jr. Day eh?
mmm...well it depends a lot on how much you wanna spend. I rapped some #'* into the Dyno2003 sim software and came up with:
'63 cam, ported heads, rockers, 10.1:1 CR, smaltube headers and muffler:
258hp@5500rpm 278#@4000rpm
Same but 8.5:1 CR, no headers:
211hp@5500rpm 240#@4000rpm
Not sure of its accuracy but I got renewed confidence yesterday when Horsepower Tv used the exact same program while they were building an engine and it came up within like 3hp of actual dyno results. Of course it is their job to sell the stuff though. In anycase I wouldn't live by it, but it should get you in the ballpark.

If you ported and milled the heads and LIM, i think that you would be able to take more advantage of a cam and or rockers.
Aren't the series one heads not so good in terms of flow? (someone correct me if i'm way off base)
and that compression ratio isn't helping you.
And if you got a metal UIM you could port match it to a series 1 L67 TB (maybe?)

His SLE is probably lighter too and if he puts a 3.33 diff in there that a few tenths right there.
