I'd throw the standard 318 in with a few basic upgrades: Coil / Leads / NGK plugs Intake & 600cfm 4bbl Headers That should get the car running easily. You can even just use all the stock gear (the above is in order of preference) but I would definitely put a true 12v coil in it so you can...

Yeah I can understand the frustration as well - people chiming in with somewhat complicated and lengthy discussions on the subject at hand... but not necessarily related to the original question. This thread should have been over right about post 9 on page 1. - boingk

Yep, OE intakes are generally quite good for about 90% of situations. I would either get a secondhand Edelbrock Performer / Performer RPM or stick with the stock dual plane if you are worried about cost. I picked up a Crosswind back when they were a lot cheaper than they are now - about 1/3...

Depending on what deck height and dish the 408ci's pistons have you can get away with fairly stock heads. For example, if the pistons are at .025" under deck height and have a 5cc dish the 360's 72cc-ish heads will give about a 10:1 compression ratio with a standard .040" head gasket. A stock...

Sounds similar to the combo my father is running: 4.030", 4" stroke, 10.5:1 compression with alloy heads. She makes 522ft/lb of torque, with 502hp at about 4900rpm with a 220' @ .050 camshaft, with a huge reserve of torque from idle. Stays over 500hp through 5700rpm, and the torque curve is...

Shouldn't be... I'd be checking the oil level and changing to a 10W-40 or 50 ASAP. - boingk

You want your oil to be 200~220'F as that is the rated temp for its operating viscosity which is the second number in the oil spec - ie 20W-50. The engine builders would have specified a 10W-XX oil to protect things during startup. The lower first number will let you quickly build oil pressure...

What those guys said, 15 is fine. If it drives well and you're happy with it then don't worry!

Forgot link to the cam specs: 20-227-4 - Xtreme Hi-lift Hydraulic Flat Tappet Camshafts

Hi mate, glad to hear the 360 build is going strong. I've done something similar but without stroking her to 408, just a .030" overbore with Keith Black hypereutectic flat-top pistons and a Scat cast crank, topped with ported and decked 318 heads that have 2.02" and 1.64" valves fitted...

Not one of these is it? Would certainly perform a similar function - atomising fuel more efficiently. - boingk

Nope, but a decent 408 will make 500hp and half a bar of boost on top of that kind of engine will push power to somewhere near 700hp if you can keep the charge cool enough. - boingk

Not to knock an awesome build, but why such gearing in something with probably about 700hp? Actually, why would you want 700hp on the street in the first place? 500hp is HUUUGE and more than enough to blow almost anything into the weeds *if* you have traction. I would go 408ci and not worry...

You make torque at the crankshaft, and this is a moment of force that is used to calculate horsepower. The more revs you have while making that torque the more horsepower you are making - you are able to do more work due to being able to exert that moment of torque more times per minute (more...

I'd go for a feeling rather than a number, and here's the way I'd go to get your goal: While engine is out of the car, check bore wear. If acceptable, reassemble with new bearings, timing chain, and camshaft of your choice - something mild in the 1500 ~ 5500rpm range or thereabouts. If the...
