383ss Posted July 28, 2006 Report Share Posted July 28, 2006 Shouldn't really need a custom intake for it. The stock L92 intake should bolt right up with very minimal modification. As for the stroke thing, I agree with not going with the big stroke also. The gain in the extra stroke (over 4") has been proven in dyno testing to be very little gain in anything but low rpm and when it comes time to play low rpm isn't a concern. That's what stall converters are for. The longer the stroke is, the further you push the wrist pin into the ring lands which can lead to many longevity problems also. <{POST_SNAPBACK}> umm what?? can you explain? an extra .125 in stroke is ~13 cubic inches on a given V8. thats going to be 15 or so more hp depending on efficiency. I understand the concern with longevity and side loading, but saying a longer stroke isn't worth hp is not true. hell, the fastest 6spd ls1 in the country is a 4.125 stroke spinning to 8000 through the traps Quote Link to comment Share on other sites More sharing options...

adams2003 Posted November 17, 2006 Author Report Share Posted November 17, 2006 So my motor is being built. Long story so dont ask. So now im trying to decide on a cam size. Alan at futral motorsports suggested a 243\250-114. My engine builders cam guy suggested a 238/248 113LSA XER lope which seems kinda small to me. He suggested i didn't go any bigger because of the my heavy truck. What do you guys think? Keep in mind my motor is a 436ci". Quote Link to comment Share on other sites More sharing options...

zippy Posted November 17, 2006 Report Share Posted November 17, 2006 If he's using the L92 heads then he's really going to want the 10º of split between exhaust and intake duration or more. Quote Link to comment Share on other sites More sharing options...
adams2003 Posted November 17, 2006 Author Report Share Posted November 17, 2006 Yes im going with the L-92's. They will be ported though by Richard at WCCH and he thinks he will be able to get 350cfm on the intake and 250cfm on the exhaust side. Do you still think I would need such a great split between the intake and exhaust if he can get the exhaust side to flow in the 240's or 250? Also keep in mind I will be using a sheetmetal intake.
