Making a 3400 look like a 3100

[robertisaar]

actually, that trick is to help eliminate reversion.

Cam and opened heads will make a world of difference on you car. I know I am talking about a different platform, but I recently saw a ~30% increase in WHP on my BMW simply by swapping to a late model (better flowing head) head and cam - even using the same small exhaust manifolds that came with the weaker motor.

Are you allowed to modify the exhaust manifolds? Opening up the inside of them to free up a little more flow will help as well (since you can't use headers)...

i opened up my exhaust ports on my heads and made my exhaust flanges to 2 1/2 in. or 3 in.and ran pipe out in front of rear tire and i felt a difference. someone told me to paint my exhaust and run it for awhile and cut the pipe right where the paint stops burning off.i guess it has something to do with back pressure.maybe this info. will help him out. oh and ben i have a dvd of our races in pa. if you want i could send you one or maybe anyone else thats interested. remember go fast,be safe!!

yea!! in the dirt. i have a 91 beretta gt with a 3.1 5spd.i race in the dirt.it would be nice to have all the mods. that some of them are using.i am from pa.on our track some times the best handling car wins.i finally got my first this season. i have been thinking of doing a 3400 top end swap on a 3.1 short block i am building for next season.i will be checking out wo-tech. GO FAST BE SAFE!!

Where at and when? I would love to see some 60V6 short track action. I will have to think about sponsorships as I don't really have anything setup officially, and I unofficially sponsor a few people already. Racing applications certainly interest me.

I sent you a message about where i race at and everthing i hope you make it out its a blast.

Right, 3500 is a PITA to do what you are asking, so just use a 3400 block, or keep the 3100 and upgrade the top end.

there is more to the 3500 block. there is 2 place ( next to the front crank sensor and behind the flywheel) that is written 3.5L

you could even try and make a B outa bondo haha

grab a 3500 and grind the C off the block, drop that in with a healthy cam and a 3100 upper intake.

i like this the mostest!

PCM is your computer. DHP is out of business but you can still find the hardware used sometimes. Cam depends on the powerband you use. You would need new valve springs at least, and if you went with a cam bigger than what I have listed as Street, then longer pushrods are a must.

Thank you very much i can see what i can do i will be coming to you for the cam and anything else i need. Would you be interested in sponsor me by chance. if not it ok. i race here in indiana
