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,.

 

thank you for all your info and help. i am still not sure whether to buy a new stroker engine from blue print or take my old blown stroker motor to a machine shop
and have em tear it all down and use my AFR heads and rebuild my old stroker engine? it probably would be cheaper to trebuild my old engine? but it sure would be nice to have a new leak free stroker engine from Blue Print to just drop it right in? I think i could rebuild my old engine for about $3500. The new stroker engine will
run me about 7000 to 8000 dollars? i just dont know what to do? also dont know if my old engine can be rebuilt till the machine shop tears it down and looks at it?
any opinions of what i should do? i am retired and dont have a lot of dollars to throw at a new engine. but i need to get my vette up and running and back on the
street. thanks for any input or suggestions

 

I installed a 383 blueprint roller in my 62 and I have had good luck with very strong runner. When I bought mine they had one of their blocks was made in Mexico and the other in the US I got the the US block. Don’t know if it was any better just what I wanted

What machine shop are you going to use if you rebuild your old engine ?

 

So what “ blew up” in current motor??? What parts are in current motor? Crank, rods, pistons, cam heads.

 

A complete rebuild for $3500 is wishful thinking.

I like BP crate engines. Install about 1/2 dozen all very happy with. The latest a BP 383 in a 64 Coupe. It’s really nice.

 

i was going to use Main Street machine over in concord i believe his name is Kurt. recommended by a car guy friend? are u familiar with main machine??

 

current motor i believe blew a head gasket and also maybe spun a bearingl

rods a stock 350 rods pistons are domed top aluminum crank is stock 350
stock iron crank heads are AFR street eliminator heads aluminum with
slanted plugs. cam is a comp cam roller rockers 1.6 cam is a thumper cam
545 lift i think engine turns over but will not start??? had car towed home
as it died on freeway and would not start. oil smellled really bad. liked burnt oil.
got home opened hood and smell was so bac had to close hood from burnt oil smell???

 

certainly doesn’t sound good

 

Current overbore on your block? You can get rotating assembly's these days at a good price.

 

Main Machine Is owned by the younger brother of a girl I went to H/S with. I have never been there or talked to him. I have also herd good things.

There is a family owned shop in the Hayward /San Leandro area that has been in business since the mid 50's that I believe is where I would go now.

 

I put in a GMPP ZZ383 a few years ago now.

 

I cannot really make a good suggestion, because starting with the 216 babbit beater 6cyl in my 51 Chevy (in 1963), I have always built my own engines from scratch. I contemplated what I wanted and then selected pistons, heads, cam, manifold, carb, etc, etc.
