O.k.,
I'm running a .030 over 454 with forged 10:01 pistons.A set of 990 heads with 2.25 in and 1.88 ex.A Comp Cams 294 solid,Team G single plane and a Holley 850 DP.Timing is set @36* total @ 3,500 rpms.The problem is I kitted the carb during the winter and now when I run it in the shop after revving a little,flames shoot out of one side when I let off.I thought I might be too rich.78 sec 75 pri,elev.is 3,000 ft.I took it out and it runs good out of the hole but on the top she pops.Any ideas.Thanks Tim
