daddy-dec-21

is that a projected due date ?


do you have a complete engine or just a block ? with a good cam, heads and intake the stock bottom end (with good fasteners of course) will go a long way before needing to be upgraded. you dont need a stroker motor to meet your goals.

personally, i hate "shorty" headers. IMO, they arent much better than manifolds. you can get full length headers for your engine swap. i would concentrate on finding a good set of heads, some decent rods and put ARP fasteners in everything. i would also go with forged pistons since you never know when the nitrous demon may rear its ugly head Devil .

Scat cast crank is fine - I have beat on one unmercilessly. I do consider them a throw away part when you freshen one up if you beat on them a lot though - never regrind or buy a regrind. Block will have to get some clearance work on the oil pan rails and some on the bottom of the cylinders I believe (luckily it's been a while since I have done one). Ask your machine shop what they will charge to do it since some have the coordinates written down and it is a fairly quick job on a Bridgeport with a digital readout. One option if you haven't put a lot of money into rods is to buy a chinese "H" beam that has clearance built in for the camshaft. Doug Herbert sells a Pro-tech brand that is a re-boxed Scat rod - it's what I use. Other than that you will have to grind a little clearance on the corner of a rod or run a small base circle camshaft. If you run your stock rods, I second putting some ARP bolts in them - sometimes a TRW piston can be kinda heavy - and keep the rpm's down a little. I've gotta go to bed now, but I'll be back with more info. Welcome to Smokemup. Clay

Did some searching on your pistons. First problem is they have a pin height of 1.560". With a 5.7" rod you only have room left for a 3.48" stroke which makes them pistons for a 350, not a 383. They also have a huge dish (21cc) which for a 350 makes it almost impossible to make enough compression for decent power. The horsepower goals you have listed will require some decent heads. 350 hp at the wheels is approx. 440 at the crank and 400 at the wheels is around 500 at the crank. $500 for some aluminum heads is a good deal if they are usable. Some RPM heads should be fine for your goals if that's what they are. Cam is going to be getting a little radical for a daily driver at the 500 h.p. level. At the 400 h.p. level you could probably use a factory Vortec head and have a very torquey fun engine. In this case you will have to balance the rotating assembly. I don't want to be a downer but take your time and save your money to get what you need and you will be far happier in the long run. I'm sure everyone will agree with that even though I don't always follow my own advice Smile . Clay
