i want to put heads,cam and intake on my 2000 5.3l RCLB this year then a supercharger later on what would be the best combination and where to get them also want to put shift kit in and what ever eles i need to make it work any one have any ideas

 

if you have the 243's on your truck already just have them cleaned up by a good shop, get a 224/228 on a 114 lsa prolly somthing from on of the sponsors -------> or just one from thunder racing or a reputable shop! Also might consider a converter circle d or yank make good truck converters(circle d is a rep).

Prolly run the truck intake but others will chime in on that!
Good luck

 

Talk to Richard @ WCCH...GT2-3 cam, WCCH ported heads, Radix 112 w/ 90mm TB and LT's shud get u into the lo 400's at the wheels. As for tranny, shift kit & servos will hold up for a while may be longer depending on how hard u stomp on it. Otherwise level 5 is the best option...but once u get over 450rwhp, ur options are way limited and prob need a 4L80 or equiv. I have yet to hear anybody is makin a reliable daily driven 500+rwhp 4L60/65/70E. This likely all to change now with the new Camaro/Vette's. Not sure but I seem to recall they run 6L80?

 

thats were i would like to be at around 400 to 450 rwhp will i need a converter for what im doing or is the stock one ok

 

well, technically you can use the factory converter at that power level, but the cam that you will need to get there (assuming bottom end is stock) is going to leave power on the table. You would be better off matching the stall of the converter to the powerband that the cam will provide. That is one of the ways to maximize the efficiency of your combo.

If the bottom end is stroked, you can use a comparatively milder cam to get to the same power levels, which will enable you to use the stock converter, but again, power will be left on the table, because you won't be getting all you can out of the bottom end.

400 - 450 with a blower will more than likely require a cam with significant increase in duration, which ups the need of a converter to "stay in the power".
