I am considering ordering a new 383 stroker engine. i found one i kinda like thru Summit. its built by ATK. The other engines thru summit are Blue Print
engines. My question is have any of you had any experience good or bad dealing with ATK or Blue Print Engines. I am leaning toward the ATK engine but
they charge a $410 core cnarge where blue print does not have a core charge. i know they are competitors but which one should i choose?
is one any better than the other? they both offer about the same warranty. The prices are about the same,
also was wondering about the cam profile? one offers a split pattern lift and exhaust and the other offers same lift and exhaust of 591 ,
is a split pattern profile better? or does it matter if its the same lift and exhaust. also one offers a little more torke than the other engine.
just trying to figure out which is best. i was originally going to replace my blown stroker engine with a LS engine but changed my mind when i found out how
much money it would cost and i would have to change too many things; so i decided to just replace with another stroker engine which will drop right in and
wont need to buy any extra stuff except a new flywheel since the new engine is a one piece main where my old engine was a 2 piece main seal.
anyway thanks for any help and advise to guide me before i pull the trigger and order new engine/. thanks guys u are the best,.
I’ have been running the BP 383/430 for 4 years. I have 12,000 miles on it and I have had zero issues. It burns zero oil and has plenty of power for a 1966 convertible. I used my old 69 Z/28 intake and ported 2 1/2 inch exhaust manifolds. I kept the stock radiator and I have not had any overheating issues. I am running an AED 750 cfm carb which performs perfect. I bought the engine directly from Blueprint. You will need a damper and a flywheel for an externally balanced engine. I only issue I have had is it’s hard on the rear tires, LOL.
I have had three Blueprint engines. All SBC and all bullet proof. They also dyno all their engines and send you a dyno sheet like this one from my 427 fuel injected SBC in my ‘64 coupe. Highly recommended!
I've had a Blue Print 383 in my 62 since 09, Probably has 50,000 miles on it, burns about a half of quart every 3,000 not babied miles. Next to the Tremec 5-speed best thing I ever did to the car!
'63 Corvette Blue Print s/b 427 1963 Corvette Blue Print s/b 427
Last summer, I ordered a 427 stroker from Blue Print. Now has about 6k+ miles so far with no issues whatsoever. No excessive oil consumption. Does however have a drip or two from the front two piece seal design, so not exactly 100% drip free but I can live with 99%. This is my second Blue Print engine and I'm very pleased and would not hesitate to buy from them again. Since I was not connected with any engine builders in my small town, this was the best route for me to go. Summit had it out their door to me by third day.
One thing I might ad, if price is the same get it directly from Blue Print, you never know how long it might sit in Summit's warehouse.
Why would that matter? Warranty starts from purchase date. Also Summit turns over a lot of BP engines. They were out of stock a couple of months ago so anything in their inventory now would be fresh builds.

Notes:
Ready to drop in and includes fuel pump, 750 cfm carburetor, and HEI distributor. Will not clear stock Corvette hood. Passenger side dipstick. Block is drilled and tapped for clutch linkage.
They sell a low profile version with tach drive distributor. Just put one in a 64 with stock hood. Used the stock exhaust manifolds and air cleaner. Fit perfect.
With my BP engine, one goal was also to retain the stock '63 hood. Like many projects, for me it was a "learn as you go." Some things work....some things don't. I was already running a Holley HP FI system which, when installed, luckily sat lower that the stock carb. Along with a different profile aluminum intake manifold (EPS), and drop-down air cleaner base, I was able to retain the stock '63 Corvette hood without modification. I was also
able to run a good sized air cleaner (3"). The only draw back was the lower intake manifold which I may or may not have had to do? I may have been able to go with the taller intake if I was willing to thin down the air cleaner height. But in the end, I happy how it turned out.
I was ready to order a Blueprint SB 396 for my 1965 that I have been collecting engine dress up items and a factory intake and carb to disguise it as a 365 h.p. until I’d did some reading here on the forum and found that they use a Vortex type head design and some other things that were going to make this difficult. I don’t mind having to create a pvc system that allows for the no hole valve covers I wanted to use but beyond that no thanks. So, I decided I will use my born with original numbers matching 300 h.p. engine and stroke it to a 383 with Brodex aluminum heads and a 1970 speced solid lifter cam. This should produce about 400-425 flywheel h.p. and I will be satisfied with that. The engine could be put back to the 300 h.p. look if someone wanted to but I can’t imagine anyone doing that.
Yes it is under warranty but as a friend found out it is no fun pulling the engine after a few thousand miles cause the rear main leaks. Got a hold of blue print and determined engine had been at summit over 6 months. Of course inventory is low now isn't everything?
