As far as mods go, just going to a 4.2 is good, but you need
(To really make it worth it)
1. Bigger Cam
2. Bigger Intake Porting (can be added later)
3. Head Porting (kinda optional, but it is needed more on a 4.2 than a 3.8)
Simple street (stock 4.2 shortblocks) strokers are approaching 300 RWHP,
one guy hit 265/280 (RWHP/RWTQ) with my 2nd generation SPI cam and
was not even fully sorted out! We're up to 4th Generation now but now
everything I put out in a cam is totally custom for each combo. You can
get it thru www.RDMotorsport.com
