Ok so I did a poll and got tons of choices... so I may have finally figured out which way I will be going... playing with desktop dyno 2003 was perdy cool... anyhow... so I have a 1991 chevy 350 2bolt hydraulic roller cam/lifters z-28 intake holley truck avenger 670cfm carb dual exhaust and headers truck cant get out of its own way... Engine specs in the caprice it was pulled from is 195hp/295ftlb torque.. supposedly so my changes have changed it... but lets see if you think desktop dyno will be acurate... $$$ to replace... $150 - intake $300 - heads (maybe getting a full 1998 350 for $300!!!! ) $250 - Cam ___________ $700 - about right? oh yeah gaskets... $150 ________ $850 so boy that is a pretty high number... I only have enough for the cam and intake right now hopefully after ebay auctions.. then can get gaskets then save for heads I am going to go comp cams xtreme 4x4 cam.. 08-411-8 cam (hydraulic roller) vortec heads and performer dual plane intake so I have a stock sheet bigger one if needed... http://www.supermotors.org/getfile/246321/original/stock_9C1.JPG all changes except for cam bigger one if needed http://www.supermotors.org/getfile/...Avenger_DualPlane_headers_VortecHeads_9C1.JPG Worked with cam/heads/intake and all others... bigger one if needed... http://www.supermotors.org/getfile/246328/original/Worked_9C1.JPG End result = barely over 300hp and 410ftlb torque?????????? are those numbers what I can expect? if so maybe save for a crate motor... $1200 = new motor and 325hp?????
