360 292/508 cam fast simple cheap builds

Here's my combo just pulled from 73 dart
292/508 cam
kb 191 domed w valve reliefs
j heads 1.88 intakes
open plenum intake
cheap headers
msd box & dizzy
100-140 shots nos
670 cfm holley
4.56 spool
727 tf
my findings w j heads were 11.68:1 on compression
this combo doesnt wake up good until past 3000rpm. My rev limiter set at 6g motor still pulling strong
was a really fun motor on the juice
gears are a must
pulled motor down & was glad to see no apparent damage on pistons from nos.
Hope this helps
