gerg 10,871 Posted June 26, 2021 I have read that as well on the black block 302 closed chamber heads, thicker material around the short turn & bowl area, from memory read from ?Paul XF1101? He has a XF sedan drag car, runs a 351 cleveland with CNC ported closed chamber heads, ran a 9.98 when I last read up on it. was updating from earlier CNC ported 302C heads to black 302C heads that had updated CNC program chasing more HP, to get into the 9's & As I found they are rather thin in the bowl when playing on a scrap head here,Whereabouts in the bowl is that? I didn't touch mine at all when I did a quick job on mine. Just rounded off the short turn, tapered the guide boss and opened up the throat a tad.He's doing 10s on 2V heads? That's pretty up there, the better ported stockers are doing well to get mid-400s in hp.Sent from my CPH1920 using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

A.E.D who cnc ported my crossflow head told me they recently made 550hp on a 393, back when I asked them about CNC porting 2V clevo heads. 1 gerg reacted to this Share this post Link to post Share on other sites

Must really know their way around these otherwise tricky ports. They do flow well for a factory small block port but there are only incremental gains to be made by traditional methods. The biggest hurdle after all the bowl work is port placement. Hence why CHI completely moved theirs upwards with the 3V. To get the mixture to turn such a sharp angle on the 2V is a real art. I'd love to see how they do it.Sent from my CPH1920 using Tapatalk 2 Thom and CHESTNUTXE reacted to this Share this post Link to post Share on other sites

gerg 10,871 Posted June 28, 2021 wonder whether EFI helps in some regard hereI think generally, EFI really only improves driveability and economy. If a big enough carby is used, it can pretty much equal EFI in absolute terms of power and torque. A cylinder head still has to flow fuel and air in either case, so I don't think its port design would be such a factor.What I would like to see is just how much EFI could improve fuel efficiency on a clevo, as they really are gas guzzlers with carbies.Sent from my CPH1920 using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

CHESTNUTXE 7,260 Posted June 29, 2021 i guess i fluked that block and heaps of research on these 400s paid off,casting numbers i mean,hey ford did make some XE casting number 4v headed manifolds for the testing which says they were thinking of making 400 4v engines but smog killed all that ,i seen some pictures of experimental 4v manifolds wow very rare. 2 1 deankxf, gerg and Outback Jack reacted to this Share this post Link to post Share on other sites
