Fknclevo 3 Posted February 3 planning to build 250 crossflow to around 400rwhp but curious as the what anyone else has ran to do it bottom end : seen kits online with 200 rods and ross pistons is this a good kit? cant seem to really find any cranks are the standard ones good are people swapping them out for something else (e series cranks or something) are there any oiling issues and shit i should worry about? top end : planning on ports heads etc etc but what valve train parts is everyone running what kind of carb is everyone using (want to keep it carby) found exhaust manifolds and everything online what kinda of turbos is everyone using seen an ice control system for turbo crossflow is this any good? yes i understand barras and intechs are a better power route no i dont want to be told to just engine swap it, cheers for your help Share this post Link to post Share on other sites

CHESTNUTXE 7,312 Posted February 3 custom fab is needed,and lots of money i threw 10k into a carby engine and got 210 rwhp better tune would have seen maybe 240,most use the std barra turbo with good results,use std oil pump,no one makes large valves so ya have to turn down 2v clevo intakes and use chev 1.6 exhaust,you can throw 3k easy at a crossflow head to make that kind of power you are talking about,yes either ef crank or std 250 crank,another thing to consider is 3 or 4 bolt balancer ,i would start with a 84da block it has 1 piece rear main seal and larger flywheel bolts. 1 SPArKy_Dave reacted to this Share this post Link to post Share on other sites
