Have you guys heard of these heads or this company
http://www.motorsports.com/sbcaluminumsbchevycylinderheadsvortecrace.aspx
I have an 89 c1500, 5.7 tbi (with all the tbi mods), 5spd, long tubes, full exhaust, crane cams ignition and coil, 1.6 roller rockers, open element air cleaner, etc. The usual stuff.
I have a bad lifter and would like to swap cams and would like to throw some better heads on at the same time. The truck is a street truck. It's a daily driver. It is a work truck for me but it's pretty light duty work. I run a pool cleaning business, so, no heavy loads, trailers, etc.
I haven't decided on which cam for sure, I want more performance obviously but I want a lopey idle as well. I plan to stay flat tappet because I doubt my block has provisions for a hydraulic setup. I also figured I would go with a regular sbc intake and a tb adapter. So, I have questions...
Are those heads really what I think they are? Aluminum castings of the vortec heads that are so popular? What do you guys think of them. They are 2.02/1.60's. That shouldn't be an issue, should it? One of the other reasons I like them is for the weight savings. I would like to drop some nose weight off the truck. I plan to add one of the Weind superchargers later down the road. I also want to retain my 1.6 RR's, will they cause and ptv clearance issues with this head combo?
What cam recommendations do you guys have?
Seems like tbichips.com has a pretty bad wrap on tuning these things. Who do you recommend?
Will the injectors need to be upgraded or just a new regulator spring and will the stock pump be able to handle the job or does it need to be upgraded as well. It's has been replaced recently but it was just a stock replacement.
I realize some of what I have planned may not be the most cost effective in but that's ok. I like where this project is going and I intend to have fun with it. I'm not trying to make a street monster, I just want to make what I have better and more fun. I know many will say to do an ls swap but that is out of the question for the time being. If I had the time, resources, and location, it would have already been done.
