ProStocker273
MoPar N Jeep
I know its no monster mill but its what I got untill funds allow to build my 360. Its a factory bore 273 9:1com 155psi in all cylinders. Cleaned up ports on 68 318 heads, 1.88 intake stock 1.5 exahust. .039 head gaskets. Cam is a comp cam .494 lift (cant remeber rest of info) Mopar oarnge box aluminum flywheel. Tr5 edelbrock with dual 450cfm holleys. I'm running stock exhaust manifolds to dual 3" pipes that dump under rear seat. I get asked a lot what Hp its makeing. Its fun to drive with 4spd. Ill be adding some headers soon but will be 1 7/8 so they'll work with my 360stroker when built. So what do you estimate Hp/tq on this little beast. Id like to build the top end a little better it runs out of steam out 5400rpm. I need to upgrade my valve springs and put my mechanical rockers on. This motor should Rev much higher. This motor dont sound like a 273.
