Summit Racing® Hydraulic Lifters SUM-HT817

Im 90% sure yes. I know in 65 lifters changed in a few ways. From 65 to today all chevy lifters are the same. If they apper the same. Im sure they will work.

WILLIAM from VA answered on August 28, 2017

the ht817 are hydraulic lifters. the 30/30 duntov cam is a solid lifter cam shaft. the 30/30 stands for the rocker to valve clearance. .030 so the answer to your question is no. the ht817 lifters will not work.

TOM from CA answered on August 19, 2017

More information would help. If it's a solid lifter cam, no. If it's a hydraulic lifter cam yes.

JOHN from MI answered on September 05, 2017

I don't think so. If memory serves me correctly, the 3030 Duntov cam is a solid lift cam and requires solid lifters that can be adjusted at 30 thousands intake and 30 thousands exhaust.
Hence the name 30/30.

DANIEL J from OR answered on September 02, 2017

No, the duntov uses solid lifters. These are hydraulic

RONALD from TN answered on August 26, 2017

Yes

ROBERT from ID answered on January 30, 2018

Most sbc stuff is universal this includes lifters as long as they aren't roller lifters

MARVIN from NC answered on August 20, 2017

That is not a hydraulic cam.

DANIEL from CA answered on August 26, 2017

yes

JOEL from OH answered on August 26, 2017

No,,, the Duntov cam is or was back in the day a solid lifer cam,,,the "30-30" was nick name for the .030 valve lash of the solid lifers. It was an early high lift cam used in the 365 and 375 HP 327 Vette.

JAMES from NV answered on January 22, 2019

Not if it's a solid cam. They will with a hydraulic reproduction 30/30.

JOE from OH answered on August 31, 2017

I put the lifters in 1966 327 275 h.p. they worked great, should work as long as it's a hydraulic cam

GAYLE from MI answered on August 25, 2017

the 30 30 cam was a solid lifer cam , hence the .030 .030 lifter clearance measurement. The hydraulics will not work properly with a the solid cam because the ramp rate is different. May run but wont give you the performance your looking for.

ALAN from MI answered on March 27, 2018

Yes

JOHN from TX answered on August 16, 2017

No, the original 30 30 is a solid lifter cam. Comp does make a hydraulic verson.

SALLY from AZ answered on August 28, 2017

The Duntov 30/30 cam is a solid lifter cam. These are hydraulic lifters.

JOE from IN answered on June 04, 2018

no no no the 30 30 duntov cam was a solid lifter cam you can't use hydraulic lifters with that cam you need to use solid lifters

MICHEAL from PA answered on August 24, 2017

Honestly on something like this I would recommend you call a summit tech

SYLVESTER from CA answered on August 24, 2017

No.

DANIEL from CA answered on August 26, 2017

No, heck no. Duntov 30-30 is a solid lifter cam, always has been. 30-30 refers to the valve lash, which hydraulic cams don't have.

TOM from AZ answered on October 17, 2018

I can not see why they won't work as long as they fit in the lifter holes.

MUNRO from TX answered on August 28, 2017

No probably not most likely to fail best to run solids

JEFF from OR answered on December 03, 2017

No

HAROLD J from GA answered on December 07, 2017

No, at 6000rpm it. WI'll pump up and float all the valves.that's what I th8nk.

ROGER from CA answered on December 03, 2017

No if you read Summit info on Lifter they sa provide proper oiling up to 6000 rpm

DUSTIN W from OK answered on December 01, 2017

Never heard of a hydraulic lifters turning 12500 maybe solid rollers

ARMANDO from TX answered on December 03, 2017

there is no hydraulic lifter known to man that will go this high in RPM. a solid roller with titanium springs and light valve-train , heavy springs is all that will make this kind of RPM. If your lucky to get this rpm, the engine wont live long and require a lot of maintenence

ALAN from MI answered on March 27, 2018

No it won’t handle it

JOHN from AR answered on December 05, 2017

12500???.. Running a SBC at that rpm??!! Never seen or heard of that!! I've seen them go to 8500... And to answer your question, NO! You are better off with a solid lifter at a higher rpm.. I would recommend that you use a solid roller!

TIFFANY from OK answered on December 05, 2017

I would rn solids f your gonna turn it that hard

ROBERT from WA answered on December 02, 2017

Yes

DONALD from PA answered on July 07, 2017

Yes. Summit lists these same lifters for 454 and I just bought them for my 350. As long as you have or are going back with hydraulic flat tappet cam style.

CLIFFORD from GA answered on June 25, 2017

Yes.

JOE from NV answered on June 22, 2017

Yes they will fit but they will have to switch to adjustable rocker setup. That is the studs will have to be changed with new nuts. I think summit has a kit for this with everything you will need.

JAMES E from AZ answered on July 07, 2017

yes with a flat tappet cam

JOHN from AL answered on July 05, 2017

they should have the same lifter for the v454

from GA answered on June 26, 2017

No that's made for a small block that size motor Is a big block

KIMBERLY from AR answered on June 27, 2017

I don't beleive so. I believe the '91 is a roller cam.

CARL from MO answered on June 23, 2017

No

KEITH from IN answered on June 29, 2017

I'm not 100 percent sure. It's been years since I have had one apart. But I think they are the same as any other gm lifters.

RON from PA answered on November 18, 2017

I suggest you pull the pushrod cover on the side of the engine, you're going to have to anyway to replace them. Most trucks came with solid lifters in 235's and I think 1954 is the first year of a full pressure oiling system so you could swap to hydraulics with the correct cam. The only way to be sure is pull a lifter out and look, this may not be the original engine. If you have hydraulics in now then no problem, but if it's solid then a cam swap will be needed as well.

BEN from OR answered on November 28, 2017

Yes

MICHAEL from TN answered on November 15, 2017

No. In 54 they used solid lifters.

ANTHONY D from NC answered on November 28, 2017

I don't think so. A 1954 engine still uses solid lifters, so a hydronic lifter won't get any oil out of the nonexistent oil galley to work .

SHAWN from WY answered on November 27, 2017

Yes
