Asked by Jet124NJ Nov 18, 2011 at 09:16 PM about the 1970 Mercury Cougar

Question type: Car Customization

Would this combination of parts go together and what type of compression would be right for the set-up? There are no connecting rods or pistons although the cam and rockers are in place. Im thinking .030 over is all I need w/ a upgraded distributer system and maybe later on an EFI. Nothing radical, just good looking and dependable will surfice.  Thank you

Riff, Thank you for the detailed and informative reply. I did mistake a few items so let me list them again. Block: D2AE CA - 2C25 & Crank: 4MA - N/A & Balancer: D1ZE-6316-AE - N/A & Oil Pan total = ($550.00), Heads: D1ZE DA - 2C25 & 2D6 ($200.00), Intake: DOAE-9425 DA - OE5 ($120.00), Exhaust: D1ZE-9431-BA - 2D17 & DOAE-9430-G - 2E11 ($249.00). I had always thought .030 over was a minimal bore but if I can get away with less then thats the way I would like to go. If 9:1 is a good compression ratio that works for today fuels, again that would be the path to follow. Would a triple angle valve seat and valve lip be adviseable? I like the quote by Jack Rouche. I was working in the engine shop for America West Airline with a guy who was building an early ninety's mustang 5.0 and he sent an idea to Jack who inturn had one of his guys build him an "exeprimental" manifold on the house. He's agreat guy but him and Hendrick should stop flying. Riff with the new info in hand would this parts combo work? Would you recommend changing out the Intake manifold if it even works with this setup? As for the Distributor, Coil and Ignition System I will look into your suggestion as this is not something I readily know about. I am also looking into the installation of a T6 Transmision.
