Update on my 383 build
The LT4 was 10.8:1 STOCK specifically building an NA motor 11:1 is just another expression of ignorance.
The belief you needed stroke to have a torquey daily driver another expression of ignorance.
Mileage is not impacted anywhere near what people believe it will be,
Cam lift doesn't hurt manners for a "daily driver". For a DD stroker I would probably do upper 220s intake on a 110LSA lift somewhere up .580 or so, PTV should be checked but would not be an issue compression more like 11.5.
The cast cranks do not hold up though in RECENT YEARS we have seen more failures IMO it is a combination of a change in manufacturing making them weaker and power being easier to make. Thing is mediocre strokers with the cast Eagle cranks keep failing.
Stop and think about it, you can buy a Eagle cast crank for barely more than a local shop will charge to turn a stock crank undersized. That has to say something about how cheaply they are made.
Lots of guys get bent out of shape by my comments and a fair number of them later PM or email me and say something along the lines of "you were right about everything".
My car is not a racecar, favorite track is 150miles away, never been trailered to or from, lightest I ever weighed it at the track was 4155 with me. There is an Impala with the same engine setup I have but lighened and dialed in very well, that car I would call a racecar and it runs 10.9. I am giving up .6 and 6mph to keep my car more street friendly. The cam is more than I would want for a true all weather daily driver but opening up the LSA a little and losing maybe 10hp from that would be all it would take even in my heavy car.

Man some of you guys are real DICKS. Just because he posted 8 times doesn't make him stupid, it means he listens more than he talks(the reason we have 2 ears and 1 mouth). I've been on here 2 years and havent posted much just because some of the guys on this site act like they designed and built lt and ls engines for GM.
