Another one of those cheap performance engine build threads
Ok, after alot of reading of a multitude of threads and it seems that the popular choice for upping the compression and gaining torque is for a vortec head swap. I was thinking about getting the vortec heads, a new intake, new cam, and I have a holly 650 that I may use. I was also thinking about adding fuel injection a little bit down the line and did some research on a couple systems that work with the vortec heads. The engine is, as far as I know, an L48 and it has been rebuilt along with the transmission. The extent of the rebuild, I am unsure. It runs very well aside from the horrible exhaust that is currently rotting as we speak which I do plan on replacing.
So which cams should I look at

i did the exact same swap a month ago. you will love i! i used a summit 1105, but i wish i had the 1103 for more low end torque. i have about 370 hp at the crank and about 410 lbs of torque.

This cam has been suggested with the Vortec head and intake swap with good results.

aside from heads, intake, cam, carb and exhaust, is there anything else that I would need? Also, what would people suggest for headers?

other information i didn't include before was that this car is going to be a daily driver and I am looking to acheive about the 300hp mark. I want low-end power/torque as I probably won't be tracking the car and it will primarily be used on the street. I just desire a few more ponies under the hood.
Is there any better option aside from vortecs? (offer similar performance - bang for the buck)

So i've been talking with a few members about the zz4 aluminum heads which have a 58cc. I would also put on a performer manifold, the summit 1103 cam, and there would be new exhaust as well. With this setup, would I be fine running 87 octane, or should I really use a higher octane gasoline?
