Re: 110* LSA TPI cam
If your going with TPI and MAF think I would
stick to 112 LSA unless going to chip modifications.
My recommendation would be to call a Cam Co.
and tech with all your info and thier recommendations.
I have always used Comp.
Changing a cam kit out not like changing intakes, its
usually there for the long haul.

Re: 110* LSA TPI cam
How did it run with the stock chip? Was it laggy at all? I just dont want it to be a dog without a tune. Im excitied if this is the case, it will save me a TON on my top end, may be able to get some roller rockers!

Re: 110* LSA TPI cam
i ran the comp cams 286hr10 in a few L98s i had that cam was nice and made great power the specs
230/230 560/560 110 w/1.5s
i have run it in both SD and MAF systems the SD car really has to be tuned but the maf can get by but you will have a little cam surge

thats the cam im runnin on my speed density TPI. it doesnt like it when its cold idles real rough, but once it warms up and the comp kicks in it does great. still aint got around to gettin it tuned... but i;ve also done quite a bit to the heads and intake to help it flow up top.

I have the 2032 and I am happy with it. It isn't too radical and I dont think you would need a tune.

Re: 110* LSA TPI cam
I got about 12-15 hours in the heads, the intake is gonna be tuff, this tpi stuff is still foreign to me, im not even sure where to start, port matching the intake to heads is obv, and then maybe upper plenum to runners
#15
Re: 110* LSA TPI cam
go back through some of the pages and see what others have done and itll; help ya alot. i just siamesed the intake about 2 inchs in and did quite a bit of port work to the bottom of intake. but make sure you aint over doin with your heads. because if your heads are to big for the tpi youll just lose velocity and effefincy within the system its all about matchin everything togethor..

Re: 110* LSA TPI cam
When I installed a new 5.0 liter engine with headers I had a Comp Cam installed that had a 110 degrees LSA. The cam was part number 12-408-8 grind number XR258HR. I have not had a problem with dropping down to 110 degrees.

Re: 110* LSA TPI cam
I tuned a car with a 2032 camshaft. It was 290 RWHP on the dyno before I started, and 303 RWHP afterwards. It'll run on the stock chip but it'll run better if its tuned.

Re: 110* LSA TPI cam
i was told the 110 cam would not be good in a TPI motor but im runnin a 212-218 487-495 110 cam in my SD 355 and it ran good with a ton of low end...but since i changed out the inline pump to a highflow intank pump i cant even get it to start without givvin it gas and it will pop and backfire bad! I need to figure it out and get it tunnin bad i think.....this is in my 92 fullsize chevy

Of ALL the tpi swaps ive seen, this is by far the CLEANEST one, you sir have done a VERY nice job with your truck and i congratulate you. As far as that cam, how do you like it does it pull to 5k RPM alright, judging by the video it has a ton of grunt

Re: 110* LSA TPI cam
At the time the new engine was installed my mechanic contacted Comp Cams and they recommended that cam. My engine runs and idles very good. I noticed a lot more torque from the new engine, cam and headers. I still have not had a custom PROM chip burnt for the ECM as I have been doing other up grades. The last up grade will be new heads to replace the 187 swirl port heads, then I will get a custom chip burnt.

Re: 110* LSA TPI cam
Thank you for the comment chev4life! Its a work in progress but one day it will get there lol...u know how it is im sure! The truck was a v6 5spd and i did the 356 TPI 700r4 swap
yea with my seamed and ported plenum and slp runners i helped out a lot with top end....back when it ran alright it would pulled good to 5 grand....but the low it and mid it out of control lol to much fun on the streets. Im runnin 315/35s in the rear and i can spin them well into 2nt. it can get a loose fast thats fosure! Next im lookin for a nice set of aluminum heads and might step up a few sizes in a cam! From the info in the thread i might look into the 218-224 110 or somthin close to that. just dont want to loose all the lot end fun stuff!

Re: 110* LSA TPI cam
MAF will handle those tighter lsa cams. I have a 109 cam with loads of overlap on my 383 stealth ram and its pretty tame for what it is. Idle is choppy but i got out just about all cam surge. Needed a few more tweaks but i never got around to it. I was happy where it was at. I even have a custom 3.5" MAF setup and retuned to that with no problems at all.
that low duration doesnt have alot of overlap even with 110. SO you will be fine. 218/224 is a nice cam for TPI 218/228 isnt bad either just has lot more split which would be ok for some nitrous or a head with poor exhaust side

on that note has anyone ever run a reverse split cam on a tpi?

Re: 110* LSA TPI cam
I'm running a Comp Cams XR282HR10 with the following specs:
Duration @ 0.006": 282° / 288° Duration @ 0.050": 230° / 236°
Max Lift w/ 1.6RR: .540" / .550" Lobe Separation: 110°
CompCams told me that I couldn't tune this cam with 110 LSA on a 7730 ECM. I do admit that it was a pain in the rectal cavity to tune but I managed to do it with help from the guys at DIY_PROM. The car runs in open loop constantly.

Re: 110* LSA TPI cam
what would be the biggest 110 cam you would want to run in a 355 SD? I would like to go with a big cam but would also like to keep the low end and dp more port work to the highflow base and slps. i would like to do this to them!

Yes, TPIS parts are pretty common and they do work. You can use either an LT1 camshaft OR 1.6 rockers on the stock cam, but you cannot use both with the stock heads. The stock heads will not handle the lift. I'd go with the 1.6 rockers on the stock cam and save your money for a cam and heads swap later to go with your 350 TPI.

If you have a roller cam the Comp XFI268HR-113 is 218/224 and 113 LSA. Super fast ramps for huge lift and power while the 113 LSA makes it idle nicely.

Re: 110* LSA TPI cam
I can't overemphasize the importance of a tune after a cam swap. I am running the comp XR258HR12 in my LB9. Yes the car ran without a tune, but there were spots where it was too lean and sport where it was too rich. Fuel economy was poor. After a wide band tune my car now runs like a completely different animal. Fuel economy is also up by 3 MPG in strict stop and go city driving. The XR258HR12 is a cam that is supposed to work with the stock tune. After having it run for 10K miles without a tune, I must say that my spark plugs are done. Never underestimate what a good tune will do for you, and I mean none of that mail order stuff. Just my .

Re: 110* LSA TPI cam
By tune or wide band tune I suspect you mean burning a new chip? If so I would agree. Luckly TPI's with MAF can adjust to such engine changes; however, a custom burnt PROM will really enhance the changes

Any place that does LS1 or LT1 tuning should be able to tune your car. It is a little bit more of a pain in the behind to do our cars because every time you want to make changes you have to take the chip out. You can't interface with the computer through the diagnostic port like you can on 4th gens. Just make sure that they do this on the road under real driving conditions and not on the dyno.
