Krambo Posted January 6, 2010 Report Share Posted January 6, 2010 You need to list your power desires, money willing to spend, are you buying the motor already built or are you disassembling yours and having it machined? You can go from mild to wild with building a motor. Price could be anywhere from $4k to 20K. Quote Link to comment Share on other sites More sharing options...

Krambo Posted January 9, 2010 Report Share Posted January 9, 2010 whats the H/P on this Its a shortblock. The choice of heads and cam will play the biggest part of the HP numbers. Quote Link to comment Share on other sites More sharing options...
04CHASE Posted January 9, 2010 Report Share Posted January 9, 2010 educate yourself on what is involved in the production and installation and go from there . also consider the cost and other parts needed for the the support of such an engine . You can get a shortblock for under 4k but if your truck is bone stock now you'll spend double that in supporting mods just to have reliability.

Mr. LEP Posted January 9, 2010 Report Share Posted January 9, 2010 Thanks Krambo. Power depends on supporting parts. Depends on cylinder heads, camshaft. This same shortblock with a 2300TVS at 10psi through a 4L70 made 690whp. Shortblock will support much more than that with more fuel and proper tuning. Set up as a N/A motor should make 500whp or so.

black00chev Posted January 9, 2010 Report Share Posted January 9, 2010 I think one of these with L92 heads/intake and a mild cam should be nice for a DD with reliability. Thought 408s were made by overboring? Quote Link to comment Share on other sites More sharing options...

black00chev Posted January 9, 2010 Report Share Posted January 9, 2010 what would just the .030 get you? 406? Quote Link to comment Share on other sites More sharing options...
chpspecial Posted January 9, 2010 Report Share Posted January 9, 2010 what would just the .030 get you? 406? stock crank + .030 = 370 Quote Link to comment Share on other sites More sharing options...
Bear Posted January 9, 2010 Report Share Posted January 9, 2010 (edited) what would just the .030 get you? 406? Just an 0.030" overbore with a factory stroke will net you a 370. Late Answer!!!
