Getting to around 396cid using 880 block

To expand on my other thread about using a 400SBC with a roller cam in an L31 Vortec 350 application.


What is the best way to get to around 396 cubic inches in a GEN 1 SBC? Anyone know of any good kits, or is this a more of a select individual parts type of project?


The engine will be used in a 4000lb performance truck application. In this truck, I have to use this 4x reluctor wheel.


And the front timing cover on the left.


Fueling wont be an issue as I am using a marine MPFI intake manifold which allows conventional injectors to be used .


instead of the CSFI poppets(top of this pic)



Truck will see lots of street/strip duty. Quality higher stall torque converter will be used. 4L65e will probably be used, possible 4l80e.
28" tire.
Overall acceleration will be the focus with this truck.
Vortec hread bolt pattern will be used. Production Vortec, AFR Vortec, ETC 170 or 200, GMPP 210 Fastburn, or GMPP Small 180cc port or Large 225cc port Bowtie Vortecs are head options. Any input on heads?

thanks

peace
