one thing you guys seem to keep over looking,
his ride is close 4000lbs and he would like to
see at least 200hp.(which will be pretty easy to get but he would like to see more & not be a racer )
I think anyone of these cams would work nice
The first to me is kinda on the small side for that much weight.
1) 245/262 lobe 112 Gross lift 468/505 Dur@.050 199/207 rpm band
idle-4500
2) 262/272 Lobe 112 Gross lift 505/530 Dur@.050 207/217 rpm band
Idle-5000
3) 272/272 Lobe 112 Gross lift 530/530 Dur@.050 217/217 rpm band
Idle-5500
Pesonaly I think these would be better with a lump ported head
and will still give Good Idle as well as Vacum ,And still work well with the EFI.
again just my 2cent
