After doing my LT1/T56 swap and stuffed my rearend with a 4.11 posi me and my friend went to a dyno day in Dover,TN and the truck did pretty good for a few bolt ons and custom exhaust.

​​​​​ ​​​​​

 

Well what did it make?

 

I put it in the video description but it made 296rwhp and 328rwtq with the usual bolt ons.

 

I got a plan to see if I put a set of 1.6 rockers and a ATI balancer will send it past the 300rwhp mark.

 

The 1.6 rr will push you over the 300 mark if you are at 296 now. Not only do i recommend 1.6 rr I also like to swap to 7/16 studs,3/8 guide plates, chromolly pushrods and new valvesprings.csome say its overkill but its worth it.

 

It's always good to be precautionary in the upgrades, but I am also thinking take the engine out and do a 380ci and a bigger cam being that it's at 137,000 miles and it is about time for a rebuild.

 

Do it youll love it on that truck wiht the 6 spd
You can stay on budget, port the stockers with same valves, cleanup the intake a bit add a reasonable (not big) cam, about any header youll love it.

 

Well I found that Lingenfelter has some ported heads for $900 so I may try them later after the stroker kit and I found Lingenfelter has a .566 lift I may try during the short block rebuild.

 

What cam is it? The 211/219? If you do that combo with their CNC heads and exhaust to accommodate you should be looking at around 370rwhp, and if you do a stroker you'll be looking at a gaggle of torque. That cam in that truck will make it a hoot to drive. However if you are wanting some lope in your idle you'll want to consider a more aggressive cam profile.

 

It's the .219/.219 duration .560/.560 lift cam

 

Yep.....yo are old-school.

Not unless the dyno is aimed downhill

The best heads can be held back by a cam that 'has no legs'. In pursuit of a hi-performance stroker, this cam has no legs.

Would do good to to 350hp to the wheels IMO. On the whole, this cam is no more capable than the HOT cam.

The Comp Cams 503 is the minimum cam I'd use if the CR is less than 11.5:1. With well ported heads (let stipulate that the Lingenfelters are well ported), the 503 in a stroker can reach the 400hp range, be easily tuned, and provide great drivability.

That cam was designed more for the long runners of the TPI cars. I wouldn't use it if you are still using a short runner intake. The 211/219 cam would better suit you if you are wanting a mild cam.

I'm not sure where it's been stated the OP is looking for a "high performance stroker..." If that is the case then absolutely there are better combos out there, but for something that may only see street duty and still pass emissions the 211 cam in a stroker would be great for a truck. I had a 211/219 cam, LPE heads, LT headers with stock displacement, dynoed 370rwhp and 355rwtq. Did a best of 12.09 @ 115.5, 3750lb race weight at a sea level track. It does alright for itself for a mild street combo.

 

I don't see it.....but I'll take you on your word.

If not the dyno then the track times and mph back it up.

 

Well if I don't go LPE cam I'll go with the biggest AI cam for stock long blocks.
Ai 230 / 238 - .566" / .566" - 110 LSA
An excellent choice for 3.73-4.10 geared M6 cars. Typically makes peak power at 6200-6400rpm in stock LT1 long blocks. A4 cars need 3.73 gearing & a minimum 3400 rpm converter.

 

That may be a pretty damn good choice as well. If paired with LPE heads, they ain't no slouch!

 

I forgot the I still haven't had the ecm dyno tune yet either I just had my tuner do a tune at his home for a 93 octane and the bolt ons that I have so there might be a few horses he could squeeze out of it when I have that done.

 

I am a HUGE fan of the LPE 211/219 cam. It provides smooth power across the board. This cam is underestimated by many but always proves itself.

 

Exactly. My combo made 100rwhp more than stock, retained the same power curve (only higher) went 70,000 miles of hard driving and would still get 25 to 27mpg freeway and low 20's in town. Started hearing a tick and no valve adjustment would solve the issue. Looked through the lifter bores and voila. I definitely got my money's worth.

 

I'm probably going to save some of the extra money for AFR 195cc heads, 380ci, custom Lunati cam, and either a ported stock intake or a TPIS Super Ram.
