I am trying to be more competitive in the mud drags. I have a limited budget. I would like to build a 511ci but dont have an extra 20k. So what I am looking at within my budget, is putting a stroker in my 433 (428).
My question is: I am currently producing about 425HP and 505lb/tq, how much gain would I see by doing nothing more than installing the stroker kit? Also I am running 9.0:1 now and I want to take it up to 10:1. Would I gain enough power to justify the $$'s?

Thank you for any help.

 

Maybe Barry can answer this. He has done many stroker engines.
So far as the cost is concerned, how much is it worth to get a grin from ear to ear?
I am in the process of trying to justify purchasing a stroker for my 428 and or buying the $4,410 aluminum block with the stroker kit $2,300 for 482 ci. then paying another $1,200-$1,500 for head porting on our Edelbrock heads.
Then another $750 for roller rockers. Cashing in one CD should do it, but do I really need that grin from ear to ear.

 

My truck already gives me a grin ear to ear but, its the ram charger with a 512ci in my class that takes it away. Pulling 17" vacuum @ 1000rpm he is pulling the front wheels off the ground. In 150' of mud he is running about 1/2 to 3/4 sec. faster then I am. My truck also weighs about 2k more than his. I know if I had the funds that a 511ci FE built with in the rules would take all even with the extra weight.

 

How fast you go= how much you are willing to spend.

 

Also what kind of diet can you put the truck on to make it lighter?? I also see from time to time used stroker cranks but they get nabbed kinda quick. You can also try to fab some brackets etc here and there to remove a little weight. This other guy with the RC is his truck a race only deal with glass/carbon fiber parts?? And is yours race only or is it a street truck besides?? Can you run in class without bumpers, tailgates, hood etc?? If he's 2000lbs lighter that's a pretty good advantage. Give us some details/rules of the class your runnin. And why is he so much lighter and able to run the same class??

 

More is needed on what you engine is now? other than a 9 to 1 433"er...Because picking up 30 cubes and a point of CR..Its gonna need to breath too....

I am thinking about putting my engine into a F150. does anyone know what kind of weight diff there is? the truck i am running now is a 76 f250 with dana 60's, C6, 205. The f150 is a 1976 and has 9", 44 front,C6 with a 203.
As far as breathing goes, my heads are ported and I run a holley 770 and a performer rpm intake with headman headers - open

 

Cash in the CD and it's gone.

Build the engine and it grenade on the first pass, and it's gone gone.

That is something to grin about.

Hey Jeff how about going to an 8os style ford truck. There a lighter truck an definitly would help in the competition your in. Those seventies Fords are popular for those muddrags. But they take some power to get down the track. Ive attended two different muddrag an as far Fords are concerned Ive seen only 4 trucks from those years. All run by one family that is in to this sport real big an are usually are at the top off there class. But definitly have spent some dollars on there trucks. Im sure you know who I am talking about. This competition is really getting intense in this sport for sure. Sounds like a Dodge is raising cain with you though. Would a 460 work in your truck. Dollar wise it wouldnt be a budget breaker. Just a thought. I wont go in to names but call those guys up running those eighties Fords an tell em what your doing. If anybody knows Ford engines they do. They might be able to help you out. Good Luck an I feel your pain. Put that Dodge in his place get the blue oval on top. On another note post your question over on the offroad forum. Several muddraggers are online over there an maybe can help you. Hope this helps Good Luck. Hope to get down an see your truck race in person. On the videos your truck runs really hard from what Ive seen.

 

Yes I do know who you are talking about. And those guys do have some great trucks. I thought about looking into an early 80's f150 but I have a 76 f150 here to use. And as far as the 460 goes, I really like the old school FE!! I know I could build a 460 alot cheaper and besides I already have the 428.

 

Yah I agree with you. Its amazing what people are spending on these truck to win anymore. Good Luck. Hopefully others will chime in here an help you. 2000 lbs is a lot off weight to offset by an motor upgrade. That weight is the killer. Its a heck off a balancing act to get the right weight with the right power. Ive seen trucks to light that hurts them as bad as if they were to heavy also. This is one sport where its darn near impossible to get everything perfect for a run.

 

When you are old, you run out of time before you run out of money, so that is another factor that must be considered. Money in the bank does not do you any good when you are 6ft under.

 

But I need enough for a box to lay in. Or I could be put under in my truck.

 

At that point, I don't think it will matter, one way or the other.
