blower or stroker that is the question

[91 stang]

i am at a cross road i have in my car a 306 8.5 to1 e cam rpm heads 1.6 rockers
30psi inj. vortec intake . so it is set up for a supercharger and i had one in toand it made good power. i took it out because i keep blowing head gaskets . gave it to my nephew and found it had to be rebuilt . so he had it done and now it is his.so i guss my question is should i go back or go foward with a stroker ?

I'd do a supercharger, you must have been running lean or had too much timing in order to blow headgaskets or the heads are warped. My edelbrock heads had some warpage which caused headgaskets to blow.

Blower for sure,get a good tune

Everybody going to tell you to go with a supercharger. Stroker motors needs bigger heads to run right, but i would love to get a ride in a car with a 347 or 408 just to see what it can do. I am thinking about building a stroker motor in a couple of years for my 69 mach1, depending on work and cash flow.

I vote for Both!! No better feeling than being stroked and blown!!!

if its the relative end to your mod's.....get the charger
if its going to be a continuing build...build the motor

You beat me to it! Hahaha

 

[1BIGMOFO]

I agree with the bone! If you plan to keep the car get a decent plower with a bigger pully to keep the boost down now and build a motor on a stand (take your time and do it right).. Then when you have your longblock all ready install it, make sure its running right and go with a smaller pully!!

BAsed on your curret heads, intake and cam, you will make a lot more power by adding a Vortech superharger than you will by adding some displacement.

You can make big power either way, but a 500 hp vortech supercharged car (done right) has a lot nicer street manners and is much more practical to drive around daily than a 500 hp NA car with the really big cams & heads & compression required to make 500 hp.

If you go with the supercharger you are going to need much bigger fuel injectors (and a good tune) to make it live without blowing head gaskets. Since you have to buy new injectors anyway, skip over the 42s and go right to Seimans 60 lb injectors. Take it from someone who tunes these things every day. The 60 lb injectors will save a lot of headache and nail biting about possibly running lean.

Definitely the s/c, you can get enough power with that and your mods to be close to the max what a stock block can handle. If you want more power than that, I suggest a Dart or Boss block so you don't have to worry about splitting the block and can throw whatever you want on it.

I agree with the powder adder,but I would go with a Turbo

​

thank you guys i think i will do the stroker 331 and biuld low comp so i can put a s/c on it . i already have 60 pound inj and vortec intake . i just would like to get it ported and floded. anyone now how does it?

 

[Hoodrich racing]

Hey I would go with the stroker. There is no replacement for displacement. I don't like s/c engines. Listen I'm building a stroker n/a Boss block. All I can tell you is along time ago. Me and my Cousin put a stock block stroked to a 324 with 10 to 1 compression. A E cam Edelbrock 185 cc heads a extrude honed Cobra intake. Mac 1and5/8 Long tubes Mac 2 1/2 H pipe 2 1/2 Borla mufflers turn downs. 255 lph intank fuel pump. 75mm throttle body with matching pro m. Stock 19 pound injectors. Mass air computer with a ford motorsport Rpm extender. Set At 7500 rpm. Tremec Tko tranny King cobra clutch. Alluminum drive shaft 373 gears. Hotchkis upper and lowers. Kenny brown sub frame connectors. A full weight 92 GT with every thing in it even the spare tire. 17 inc Roh wheels and Nitto 275/45/17 in the back. Car went 12:00 as is on motor. No juice no supercharger no welds skinny and fats. And we wipped plenty of supercharged cars. No drivablity problem. A killer sleeper with leather interior AC power eveything. Car had alot more in it. But we sold it years ago. And that was All done on a budget. So yea I go stroker.

​

 

[Glueyes]

Really? And there tons of stock motor,full weight cars with turbos that are running in the 10's all day..I would just slap a power adder on it unless you decide to use an after market block..If your looking to build a stroker with a decent HCI and a power adder on a stock block,waste of money..Just my 02 been down that road already

​

 

[irishpwr46]

forget the stroker. the only reason to go with a stroker motor is to replace a broken motor. especially since the car is already built for boost. i would also go with a turbo.

 

[slvrgt]

I would do both. The white car I had, had a 351 bored and stroked to a 396 the first pass after i had the motor refreshed was a 9.83. that is right out of the 'box' nothing else done to it. Now, im looking @ either a 427ci small block or the 557ci big block. What ever one i go with is going to have a turbo!

 

[dsblk93gt]

Depends on the budget but for the $$ a used Vortech kit would be the best bang for the buck. I'm running a BA2400 meter and 60lbers and tune my car myself and the 60lbers are awesome, even with the cam I have great driveability. I kind of wish I had kept the stock cam though. I like the ability of a forced induction car to drive almost like stock but capable of being MUCH faster when you are on it.

Ok just go a pro charger and have to get some more parts and wouldn't you know ,I found a 351c roller with low miles so I think I am going for some more money . Thank gog spring is coming .
