5.0 magazine has an article on the new BOSS block. Much beefier than the current R block. You should see the size of the 4 bolt mains! Supposedly, it's a little cheaper than the R block too.

I know guys that can break an anvil with a ballpeen. My primary power adder is light weight, the car will have to have balast added to make EM minimum weight. I like the looks of the "New" Boss block but the added strength would have to add weight which narrows the weight gap between the 5.0 & 5.7. In addition it adds nearly 2k to the build cost. I bought a fresh 5.7 from a wrecked F150 for $150 that, with a cam change, will be run as bought and a roller core (broken piston?) for $125 which will have a stroker crank and pistons added. The reality, other than bragging rights, at less than 1800 lb and over 500 hp the amount of time that you are on it will be limited.

Build the motor you have. Don't second guess yourself. You will always scare the crap out of yourself in any cobra. A high compression 347 sound awsome. Once you get on the road with your cobra you won't care what motor you have until you run into another cobra! All cobras are the same. Enough power to tool around town and crush anything made in Detroit at any moment.

Hi Tech

What cam are you going to use?

I ordered a XE282HR Cam with a custom grind. They are changing the lobe sep from 112 to 110 for the carb,

here are the specs:

I have a Proform 750 (mech secondaries) for the 347. AFR 185's on the way. The cam helped make that decision for me (see my last port for cam specs, I got the same cam custom ground with a 110 lobe sep). The GT-40x heads are heading to ebay. Even with the incredible port job, I believe the AFR's will be better.

I sure hope the stock roller block holds together, I'm shooting for 450hp at the flywheel.

Does anyone know if the oil valley girdle works?

What about the oil pump, I read somewhere a HV oil pump puts lots of strain on the distributor gear. Would a standard one work better?
