Wow! This is one of the best threads that I've come across. After reading about all the manster engine people are putting in their Cobras, I was starting to feel embarrased about using a paltry 390 FE in my Johnex (from the guys that picked up the pieces when Johnex came apart). It gladdens my heart to see that I am not alone in putting together a moderate engine. I think that the direction we are heading with these will provide a reliable, streetable engine while still delivering while still delivering enough punch to get your adrenalin flowing.
The 390 that I'm having put together will have a Weiand single plane intake (very low profile) and the original heads from the "68 Galaxie with a little port and bowl work. My engine builder tends to be pretty conservative when it comes to bolt ons. His recommendation is to convert the distributor over to electronic trigger (Pertronix) and use a Ford blue grommet box for ignition control. He reasons that this setup will easily handle the RPM's that the FE will turn, and spare ignition units, while they rarely fail, are inexpensive and very readily available. He has made some oiling system mods, most importantly in the
oil pump and filter adapter attachment area. He is also using a custom Canton pan with rear pickup. Compression is being kept in the 9.5:1 range to deal with today's pump gas and keep away from special fuels and octane boosters etc. The target for this engine is 450 HP. The dyno will let us know how we did.
I am building this car to drive, and the less hassles that I have that take away from the enjoyment of doing that, the happier I will be!
Seems that I'm not alone in that approach.
PJS50 - I'm in the same boat as you concerning go fast cars. Had lots when I was younger - then marriage - then kids - then mini-vans and sedans. It's been way too long!
