Spyders Engine Rebuild - 302 to 331

[Spyder]

well, i would suggest getting a stroker kit from summit or jegs. Usually forged pistons are minimum, but i would suggest getting forged rods too.

Then your gonna need some nice heads, so that your not starving the new stroker. I would suggest Trickflow or AFR

You gonna want a cam shaft to take advantage of the new setup, if i had to do it again, i would get a custom grind.

You would be better off with a new intake manifold as well as new throttle body and MAF. Maybe even injectors too


I would say that is about the basics, you can make it happen with a lot less, but if you doing a full rebuild, you might as well do it right the first time.

sp spyder hows it running?

 

[Spyder]

Car actually runs great!!

Had a few surprising races over the past few weeks, not too mention its holding up real well in the Vegas heat.

Oh, keep this quiet, but i got over 30mpg when i moved from Salt lake to Vegas!!! :noes:

:gtfo:

hold the phone! You got 30mpg in THAT beast?!?! dizamn!

 

[Spyder]

Well, im bringing this thread back from the dead.

The 306 has been taken apart and is back in the machine shop to get freshened up and get a little bump in compression. GOnna be looking at about 11:1 this time around. SHould be quite the little beast when thats all complete.

I hate to think about this, but im getting very tempted to sell the cobra this winter/spring.

But we will see what the fresh motor does when its all back together

 

[Javi]

what are the plans for the car?

 

[Spyder]

Well, just running the same NA combo that was there before, other than bumping the compression a little bit.

I may end up selling the car though, so nothing too drastic right now

 

[Dalamar]

didn't we take some pictures of the dissasemble?

 

[Spyder]

Hmm, i dont know if we did. You will ahve to check your camera and see.

wow, just read this whole topic! awesome thread guys! can't see the video though
How does the cobra intake work on that 331? i'm using a ported-lower, cobra for now on my 347 cause of the low-end torque they are supposed to have.

once again, great thread and get some more pics up if you can!

 

[hottwheels04]

but its about how fast you go not how high you rev it



so i was happy with the performance

11.60s all day on motor with a car with full leather interrior with a set 26.8.5 15 slick on a 88 lincoln town car rim and dangled a 17 inch cobra wheel i dont think i did too bad

thats what im talking about full weight street car with leather seats running mid 11's n/a gotta love the ol pushrod

The GT40/Cobra design is a TORQUE monster.

Well, just got some more parts to the machine shope.

Looks like the damage was a spun rear main bearing. Gonna be doing a line hone and slappin everything back together with some thinner head gaskets to take the compression to roughly 11:1.

Should have the long block back together in about a week or so, then Dalamar and I will be stuffing it back in. Just in time for the snow....yay

But, its looking more and more likely as though i will be letting her go this spring. Gotta get a house and getting started on the new secret weapon for the streets!!
