Best 273 and 318 builds (NO 360's please)

My 318 build for my 97 dak ended up with 247 rwhp, 265 rwtq and a useless first gear!:)
That works out to around 340~ hp at the crank.


Mag heads ported
1.7 roller rockers
R/T cam 204/208 @.050" 114 centreline
M1 intake for magnum FI
ported TB
edelbrock shorty headers
flowmaster catback
Compression is around 9.1

I use the hypertech power programmer which I believe is limiting the engine a bit on the top end, but a fun drive nonetheless.
