been looking around a bit and notice that most people had the DD 5.3l build. im looking to build up one with a max of 383cid for a project but would be for street racing no towing or daily driving, still able to drive to the track and back home, a street motor. any one got somthing along the lines? it will be going in a 88 mustang. big cam, good heads, good flowing exhaust.... anyone got somthing around about this? im looking for ideas on intakes cams heads etc..

Good Luck....i've never heard of anyone boring the motor out that far. i've read that you can bore to a 5.7 but that's all.

I'd rather just a sickass 5.3 with either high compression and a shot or low compression with a badass FI system.

I'm planning on going H/C on my 5.3, with some ET performance heads, and then a bigger converter. I'm looking for mid-high 12s. I'm shooting to be about almost as quick as TXsilverado, but he has a 5.7.

And it will still be my daily driver.

You might want to PM PappyDan about doing this. In https://www.performancetrucks.net/fo...d.php?t=410300 thread, he mentioned this option.

346ci is the largest you're going to be able to go with a 5.3 block. if you want a 383ci go with an ls1/ls6 aluminum block. the aluminum ls1/ls6 block will save some weight and they make 383 kits all over the place..

You could do a 383 with a 4.000 stroke and 3.90 bore.

You can bore the 5.3l block to 3.90" and add a 4.0" stroke crank which will give you a 383. With a pair of 243 heads on top this will make an awesome combination for a truck.

Good luck,

A friend of mine has a foxbody with a turbo 5.3, nothing special just a standard inch block with a mild cam, some porting, turbo and a tune and he is pulling 11.2's not completely tuned. (good for low 10's according to mph) and he's driven long trips on a th400 trans with decent mileage. maybe try a boosted setup verse more cubes?

i did think about a boost set up as well. im not leaning toward a 383 jsut dont want anything bigger. i would like to keep it a stock cube motor with high cr and some juice. good heads good exhaust and a nitrous cam. ive read a few places that a junk yard 350 with iron heads and some spray will run a damn good time but i would like to keep it fuel injected for the trips to and from the local spots. just wondering if anyone had some input on where to start. im not familiar with these engines very much and dont know what they like.for the car is still stock suspension with th350. would just like to have a good streetable car. what parts would you build yours with and why?

Intake: Fast90/Victor JR/Super Victor if it fits under your hood
Heads: WCCH Edelbrock 245
Cam: 24x/24x .600"
Shot size: Size accordingly if you need more
Cubes: 364" ls2 block with 24x 3.62" crank, 4" Wiseco flat pistons

Should be good for 500 rwhp N/A if that meets your goal.
