small 6 vs. big 4, help with the basics... Options

[jonferns]

was considering a 2.7-ish engine for a shell that I have. After reviewing what is necessary, I am starting to think that a big four is sufficient.

what is the normal power output for a 2056, and can that setup run on FI?

looking for something with a bit more power than what we have. Currently have a spare 2.0 out of a '75/'76 sitting in the garage...

thanks! -JON

The Stinson heads are probably cheaper than ours and based on back to back comparisons are less effective both on the flow bench and the dyno.

As for 356 power, well I have build a 167HP PUMP GAS 356 engine, making power with those engines is VERY SIMPLE compared to the Type 4 platform. As we speak I am building a twin plugged 1500cc engine for Land Speed racing based on the 356 platform- it'll make over 190 HP and spin 10,000 RPM. The 356 engine and the type 4 share NONE of the same characteristics except the firing order, the biggest mistake that can be made is manipulating the TIV with similar mind set to that of another engine- especially the 356 platform.

You more than likely don't need 13:1 to make the most effective power for your application and with camshafts bigger is NOT better, especially if you experience port stall due to the cam choice. With the TIV bigger is usually LESS EFFECTIVE, my development and back to back comparisons have proven this time and time again.

Heads, cam induction and exhaust are all dependant upon each other and you can't get an optimized engine by dealing with people who haven't developed the entire engine or do not offer an optimized combination proven to work. It takes more than just a pair of heads, more than just some compression and more than a huge cam to make usable, efficient power.

It's all in the combo.
