with 4k you can get a 408 and resell ur current engine or shortblock and make some money of of it and save a bit for the 408

prices seem pretty reasonable on labor...except for assembly maybe. Most shops will assemble pretty cheap when they do the rest of the machining work from my experience.

Will the 408 make enough power to offset the weight increase over the 383? When properly thought out, the 383 will make very similar power to the 408.

I would check and see what they would charge to verify that you have oil pressure after its assembled. My builder didn't check so now I may have to pull the motor back out. This may be rare but what a pain!

Thanks guys I believe Ill still use my block haggle a little labor out of them and it would be fair. Im just not going with there parts just might buy tsp rotating assembly 383 and take the optional upgrades for the better rings and -15cc pistons. for like $1750.00 and not pay tax thru online so in all I save about 400 or more off the estimate.. So what you think Imm ready to get this over with spend my load and get back in my ride...

Heres what im looking at and taking the upgrades comes out to 2200 on parts and then let him do the block work and tell him assembly around 200 seems fair..

You can buy a rotating assembly from ls1speed that has better **** and it comes with bearings and is already balanced and is 2388 for it.

he can get an ls2. 383 is a waist of time in my opinion. ur going to want more cubes eventually. might as well get it now for the same price.

for everyone saying 383 isnt worth it FWIW my 383 makes 500rwhp NA and ways 100 lbs lighter than an lq9 408 if your going with a blower, turbo or spray over a 200 shot in the future go with the 408 if not you really dont need an iron block just more weight on the nose of the car which makes it turn like a pig. my buddy had a 408 in his SS made about the same maybe a little less than my motor cars were almost even HP wise. both cars were M6s and we both had moser 12 bolts. my car would easily pull 5 to 6 cars on him in a quarter mile. my car hooked up better and pulled harder. he ended up flipping it like 5 times on a back country road when the *** end came around on him while taking a corner. if your shooting for over 700rwhp FI in a drag car than go with the 408.

Then dont use an iron block on the 408. Build an LS2 based motor.

The main advantage to a 400+ inch motor is the 4.0X bore. You can get much better flowing heads.

If given the choice between a 383 LS1 motor, or a 370 LS2 Motor, i would pick the 370 every time because of the larger bore.

He's going to be cramming air in via turbocharger, so all of that kind of goes right out the window.

As far as parts go, the pricing is good. You could find cheaper parts, but the K1 stuff is pretty nice and Wiseco is top notch. With the machine shop being local to you, if you have a problem with the engine, shipping won't be an issue in getting it fixed. Ask some people who mail ordered their engine, and they'll tell you the same. Good luck with the build, and keep us posted.

It was more aimed at the post above mine than the OP.

If i were the OP, i would build a stock stroke motor instead of a 383. It would be cheaper and handle the power just as well.

I can build you a HKE precision racing engine 408 for that money or a 383 for $3775 Using Wiseco pistons.
You'll make more power with the 408

Not to nit-pick that, but we offer it with the Callies Compstar crank and rods, Mahle pistons and rings, bearings and balanced for $2379.99. Their site has it for $2388.99

Sounds like a nice build. What kind of car is it going in?

themack56

iTrader: (70)

your not comparing apples to apples. how big is your cam? how big is his? what kind of heads you have? what kind of heads does he have? what do they flow? what are the supporting mods on both cars? weight reductions on any car? does he know how to drive? the 408 can make more power period.

true i had my 383 when 408s werent around but i did build my top end up after he had his built so i prolly got better top end parts parts, other than that the cars were identical in fact he had 4.10 gears i had 3.73's. its weird i see some people with 408s making over 520 at the wheels then i see some that making less than 470 at the wheels, its really all in the motor setup you can make more with a 408 if you build it right. the next motor i will be building will be a 414 with twin 67's just gotta get my money right.

agreed. most people just slap parts together and bitch and cry about why they didnt get the same amount of pwer as the other guy. its all in the parts an dmatching the heads to the cam. that why a custom grind cam is the way to go. tony over at afr can grind custom cams for his heads. obviously hes knows what makes his own heads move. when i get my 427 ls1 mid darton block assembled. i will be going with tonys new 245cc afr heads and a custom grind cam. should be good for all day 10s and with some weight reduction and slicks high 9s is a possible dream. the best advise i can give to the op is do research on parts and combos. dont mismatch ur stuff. you can have the best flowing heads on the market and a cam that is meant for l92 heads, then you wont get what the results you want.
