Done a little math. Blower will add 30% more power(plus or minus). I chose a lower number because I am going to do this as cheap as possible. I start with a "free" junk yard 305. These things might make 150 hp.
Ill round up to 200 HP. I buy a blower cam from summit$99.00,I buy the rest of the cam kit another 200. Buy a gasket kit and timing chain 150.Now I tackle the heads,again going el cheapo.I buy a porting tool and porting kit,250. After spending 40 hours porting my heads I go to the machine shop and get a valve grind, 150 machine shop time. I buy a used intake 100, a used carb and rebuild kit 150. I look around and find a used ignition with timing retard 200. I buy a cheap blower 2200.I will add in 500 more to adapt the blower,maybe replace the hood. other misc items,like plumb oil line etc to blower,different brackets and pulleys,,,,
looks like I now have a 200 HP engine that now make 260 hp?I super tune the engine and make 310 maybe 330HP? all for less than 4k
The engine was free(or cheap). It will last ????until I break it
Thats is 1500 bucks cheaper than buying a brand new 415 HP roller cam 350 turn key engine with 2 year warranty that also has dart shp heads
