New old '66 Barracuda

So far I have had the car out a few times in the neighborhood - down to the car wash, a beer run, etc. The lower radiator hose was leaking so I replaced that on Saturday, then took it for a spin - I've noticed the temp goes up real quick, so I went home. Strange, when I bought the car and drove it home about 20 miles the temp never got very high (20 degrees cooler outside then). Now, keep in mind, this was also with the original 2 barrel. Since replacing with the 4 barrel Edelbrock it warms up pretty quick but I do notice it getting pretty darn hot... What is normal??
Yes, I have had a couple leaks show up that I didn't have before, but it actually leaks less now than when I got it! But, I do have a concern on the lubrication - I mentioned it the valve train and valley looked pretty dry when I opened it up, so I'm wondering if there could be enough restriction somewhere in the oiling lines to prevent flow to the heads? Would this influence the overheating? Oil pressure is good... Last oil flush was pretty nasty and now it is still nice and clean.

On another note - in a different thread I had posed the question of 340 vs. 360 with lots of input. I was thrilled to find a Magnum 360 for sale locally, listed as complete from a running vehicle - picked it up on Saturday afternoon and tore into it that evening only to find... missing a piston and a crack between the valves on the same cylinder. ARRGGGHHH:angry7: I was tempted to call the seller at 10:30 p.m. when I discovered this but figured that wouldn't be conducive to getting my money back. Fortunately, in the morning when I explained to him what I found he told me to bring the motor back for a refund. Upstanding guy - thanks M. in Lynnwood. So, the search is on again...
Since I didn't get any response when I posted this in my 340 vs 360 post, I thought I'd try it here. This is in regard to building a 408 stroker -

Thanks all, for your replies. Didn't mean to leave the thread hanging with all the input and no response... Busy with the day job, night job (15 y.o. daughter - lot's of overtime!) and had a work related trip to Central America...
But - I did manage to find a 360 Magnum local for a fair price. I went through and re-read the posts here and now have a bit to consider - the motor is a completer runner, with almost all ancillaries included. This means if I want to I can retain the fuel injection. I also ordered a couple of the "How to..." books - Larry Shepard's How to Hot Rod SB Mopar Motors and Jim Szilagyi's How to Build Big Inch Mopar SB, the latter of which is very informative. In particular I found his recipes on 6 different engine packages interesting. Anyone here have any experience with his 'recipes'? I am specifically interested in the Magnum Muscle Car 408 build, as the motor I'm buying is the basic core for what is laid out. For those who haven't seen the breakdown, here it is -

4.030 bore / 4.000 stroke
block - Magnum 5.9l
Crank - Forged Mopar #P5007254 - internally balanced
Damper - stock 318 w/ neutral balance
Rods - Eagle SIR
Pistons/Rings - Diamond #51405, Speed pro moly
Oil pan and pump - Moroso deep sump # 20730, p/u #24700, Mopar #P4286589
Cam - Hyd roller cam - Mopar #P4876348 230/234 dur. @ .050, .0501/.513 lift, 108 deg. centerline
Tappets - Hyd. roller - included w/ cam
Pushrods - Stock Magnum
Rocker Arms - Stock Magnum
Cylinder Heads - Mopar Magnum R/T - Big Valve #P5007141 w/ porting done
Intake - Mopar M1 Single PLane #P5007380
Carb - Holley 750 cfm
Ignition - Mopar #P3690426
Ign. timing - 35 deg.


The claim is that it will make 505HP @ 5900 and 525 ft-lb @ 3800. Seems impressive... Realistic??

I'm going to price out parts to stroke it. I already have a pretty good idea of the bill at the machine shop. Then there's the whole transmission component to determine...

Another day.

Any input??

Thanks guys.
