In the above combination, the Eagle cast 4.500 crankshaft should be able to hold the 6500 rpm limit no problem assuming good tune. Not the most fitting cam choice for the upper rpm range of a 4.50 stroker but the tunnel ram will certainly help.

Given the 6500 rpm limit, my personal opinion is that you should ditch the 1/2-grooved Clevite 77 main hearings and switch to either a 3/4-groove performance bearing (such as the Federal Mogul/Speed Pro Z134M) or a fully-grooved main bearing (such as the Federal Mogul Z4907M).

Paul the Blue thunder intake is a dual plane dual carb piece like what the factory would have offered if they had offered a dual quad option on 429's. Bluethunder is the only company that makes them. Seen one years ago on a Thunderbolt clone that had a 501 in it. The rated rpm range on them is 15-6500. They would make a nice intake on a resto-mod!

Over-all I think the combo looks good, there are better cams than the 305H though as far as power production.

Marcelo, if the engine is already together and running in the TBird, then don't worry about the bearings. Clevite brand bearings are fine; my preference for the 3/4-groove or fully-grooved is in the interest of longer oil feed to the rod bearings. If the engine is running fine, then great. When you remove the engine for any reason, change the bearings but it is not necessary to remove the engine speicifcally for this purpose if it is working well now.

That's the first plug I've heard for Federal "Mongrel" bearings in a long time.

Hello Marcelo, nice car!! I am curious where are you ordering parts from?
if imported is it taxed?
Also what is the law on importing cars to Argentina? I have read online that it is not possible unless car dealership is involved.
