How Much HP??
Okay,
I have a recently rebuilt LG4 rated at 150 ponies.
Add,
4bbl 14" K&N Edelbrock Carb, Edelbrock dual plane intake, Hooker 2055's and 3" Edelbrock catback. also a Moroso blue super ignition system. also a cam 214/224 with a rpm range of 2000-4500 I have removed A/C and clutch Fan.
This is my first domestic and I am hoping someone can give me a good idea about what im looking at for hp ?. I bought this mistaking it for a 350. I already took it apart and found it recently rebuilt. These are all parts I have in my pocession awaiting installation.
Thanks in advance

I'd put you in the 250ish hp ballpark tuned well.
CHP or CarCraft did a LG4 bolt on test and got 269 hp I believe it was w/ a slightly hotter cam than you're using (CC XE262), a Performer RPM (I'm assuming you have a standard Performer) and longtube dyno headers. Figure you're losing some over their results on each of those areas, and 250ish is what I'm thinking, just my .02...
