I recently blew-up a piston in my 427 FE center oiler.
The piston is in multiple pieces (none of which is bigger than a nickle), bent the connecting rod and put a 2 1/2" hole in the cylinder wall.
The majority of the time the Cobra is on the street (+/- 95%). I track it out at Purhump (outside Las Vegas) and Willow Springs 4 or 5 times a year.
I'd like to keep the re-build under $10,000., but don't know if that is possible and still be able to put the Cobra on the track a few times a year.
It's time to rebuild but I have a few questions and need your help:
1. If I can't sleeve the cylinder, do I go aluminum or cast iron block.
2. If aluminum block, is a Pond or Genesis better?
3. If aluminum block, can I still use my iron heads and intake?
4. If not, what heads should I use?
5. If cast iron, do I use a junk yard block or use Genesis iron block?
6. What crankshaft, rods and pistons should I use?
7. Or is it better to start over with a crate motor?
What are some of your opinions?
