Blueprint Engines in Jegs 383

I was wondering what some of you think of the Blueprint engines in Jegs. I was going to take one of their 383 short blocks and stuff my AFR 195's on to it. I was wondering if any of you have any experience with them regarding how good their machine work is and attention to detail. Would i be better of just going to my local high performance machine shop and have them build one for me or just go with one of the mail order short blocks. How do you think this compairs to the GM 383 short block from GM performance. I believe that the ones from Gm are close to 2500 for the short block vs. 1799 from blueprint engines which sounds pretty reasonable.

My car is a 67 camaro with a 700R4 and 3.55 gears. This will not be a drag car but more of a show car with some go. I have a 350 in it now but want to upgrade during the upcomming winter. The engine will see 6300 or so RPM every now and then, I have a heavy foot thats why i have some concerns regarding the short block from blueprint. thanks for any input.
Ron

I would suspect that the short block from Jegs contains a fair number of Chinese parts. Of course the GM short block would contain some Mexican parts, but at least they are GM certified.

Re: Blueprint engines from Jegs

While the engine described is not a racing engine (I.E. all forged stuff) it has pretty good things in it. I think that Jegs wouldn't risk selling junk!!!

all i can say is you will get what you payed for. and i am speaking from experience lets just say i went with a short block that an unnamed man that has a t.v show building hot rods used in one of his cars we both purchased our engine from the same guy, but i got a bad engine and ended up loosing way way more than if i would have if just paid the extra money to have a local RACING ENGINE BUILDER build it in the first place . maybe if i had my own t.v show they would have showed me the respect i deserve as a paying customer. oh well lesson learned. just trying to save you the head ache.

383

Thanks for the replies. I believe the Blueprint engines have a scat rotating assembly and they are balanced. They also have Hyper.... pistons. Has anyone here ever run one of these? thanks

maybe blueprint does really good work maybe they don't. if they don't then you will have to ship it back to them and and it will cost more than if you would have just paid the extra cost of having a local performance engine build.

it's not the quality of the parts you should be concerned about it is the actual machining and assembly.as my problem was not with the parts.
i used 4340 forged crank/h beam rods and forged pistons. are you will to lose $3000+ on 1, 2 or 3 guys opinion in here.


i was given 3 options

option 1) to send my engine back to the guy who built it to fix.

2) i can get all my money back $2500 for the short block.

3) i keep all my parts and get 1200 dollars back.

i chose op 3 there's no way i would have them touch my engine again PERIOD.now it is going to cost me 2000 more to fix it right.on top of the 1100 i lost paying a mechanic to r&r my engine and a machine shop to assemble the long block b/c i wanted the cam degreed. from now on any engine i buy will be built locally by a racing engine builder. i don't care what the cost will be up front or how long i have to wait if they are backed up with engine orders.as i am sure that it will be cheaper than fixing it again.

and as for scat -many people have used scat cranks and rods up to 500 hp +.

383

Thanks for the reply and the warning. I will take that into consideration. Their still is a little time for me to think about it before winter hits, and maybe the GM short block is the way to go. Does anyone know what internals are used in the GM short blocks. Will they hold up to around 450 Hp. Thanks
Ron

i should have gone with it i paid $2500 for mine but now $3500 is still cheaper than what i am going through.

I just had a Blueprint Engines 383 vortec stroker put in my 88 GMC Sierra about 650 miles ago. No problems encountered yet. Customer service was great. Comes with a 50,000 mile warranty. Don't order it from Jegs, go right to Blueprints website - it's cheaper. I don't race, no nitrous or huffer, so this "basic" 383 should last a while. If your really going to hammer on the motor and buzz some high rpm's I would look for a forged 383 - but obviously the price will be higher. For the price I am very happy with the Blueprint 383.

650 is not enough miles to find out if your going to have problems check back in @ 10,000 miles but i do hope you do get 100,000+ though.

to me a 383 is a performance engine and should handle anything you through it.

cast crank, forged rods hyperutectic pistons up to 500 hp

forged rods, forged crank and forged pistons 650 hp +.
