Yet Another Cam Choice/ Engine Combo Thread For 318
SRT8,
Sounds like you know what your doing,
On the budget end, I would go with the Compu-Cam 'XE-268H' Cam and Kit set-up,
stay with the Stock Converter, and go with 3.91 Gears.
Then save the money for a better set of Cylinder Head's. Those #3769973 are
functional for 'Street Use', but have limited intake flow compared to other
Mopar Small Block Cylinder Heads.
You've got a good Edelbrock Performer Intake and Holley '650-DP', and you need
some improved breathing to unleash the 'Mid-Range' power in that LA-318.
A set of 318 (#4323302 High-Swirl) Cylinder Heads would be the next best 'low-cost'
investement. High-Velocity ports, and good flow with just a little bit of work (Bowl-blending
and Gasket-port matching). The 'high-swirl' combustion chamber helps prevent detonation.
Of course installing bigger valves (1.88" Intake and 1.60" Exhaust), would be optimal,
but not completely neccessary for a Street Runner.
The #302 Cylinder Heads are usually found with a 62.0 to 65.0 CC Combsution Chamber,
so it gives you some room to mill them, and they work great with a '318' that has
between 9.5 and 10.0 Compression-Ratio. And they have 'hardened valve seats'. With
some port work, they deliver good low-end torque, and are responsive.
And eventually 'Stainless-steel Roller Rocker-arms.
